Hello!
I am using Fancy Prairie's amazing code to filter records based on multiple selections on a form. Everything works great except for one currency field. Here's the huge code in it's entirety:
The field that won't be recognized (using debug.print) is the MinValue field: TAG: Where>=masterquery.itembid; I am asking for a value >=$50,000. If I use JUST the = sign, it works. The notes in the code suggest I can use >=. Please help if you can! I thank you in advance for your assistance!!

'*
'$ Function: BuildWhere
'*
'* Author: FancyPrairie
'*
'* Date: October, 1998
'*
'* Purpose: This routine will build a Where clause based on the items the user selected/entered on a
'* Report Criteria form (or any type of form that the caller may use to build a Where clause
'* based on the items selected).
'*
'* This routine assumes that, in order for the control to be included in the criteria,
'* it must satisfy the following conditions:
'*
'* 1. Tag Property must contain: Where=TableName.FieldName,FieldType[,Operator,Value]
'* a. TableName.FieldName is the name of the Table and field to filter on
'* (example: tblEmployee.lngEmpID)
'* b. FieldType must be one of the following words: String, Date
'* (Note: String and Date are the only ones that have special meaning at this time
'* (' or #). However, if the FieldType is not String or Date then set
'* you can leave the FieldType empty or (anticipating future uses) set the FieldType
'* to Long, Integer, Byte, Single, Double, Boolean.)
'* c. Operator (optional) can be one of the following: = <> < > <= >= Like IsNull Between. Or it could specify a control on your form (i.e. forms!formName!YourControl)
'* (Default is =)
'* d. Value (optional) to be filtered on (more for option groups and check boxes)
'* (Note: This is primarily intended to be used by Option groups and check boxes.
'* For example, suppose you have a check box. If the box is checked, then
'* the you need to set the Value argument equal to True and the FieldType
'* should be set to Boolean. Else Value should be set to False.)
'* 2. Control must be Enabled
'* 3. Control must be visible
'* 4. If the control is part of a range, then the name of the control must end with
'* either _BeginR (begin range control) or _EndR (end range control)
'*
'* As of this writing, the following controls are checked:
'* 1. List Boxes (multiselect and single select)
'* 2. Ranges (2 controls that are grouped together (i.e. Begin and End Dates)
'* 3. Text Boxes
'* 4. Combo Boxes
'* 5. Option Groups
'* 6. Check Boxes
'*
'* Arguments: frm (form)
'* ----------
'* Represents the form (Report Criteria form) that contains the controls
'* from which the Where clause is to be created.
'*
'* varCtl (ParamArray)
'* -------------------
'* Indicates which controls you want checked. If this argument is missing then
'* this routine loops thru all of the controls on the form searching for the ones
'* whose tag property is set accordingly. Else it only checks the ones passed by the caller.
'*
'* NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE..NOTE
'*
'* This routine assumes that the Where clause will include the AND statement between each set of statements.
'* For Example, (strLastName = 'Smith') AND (strFirstName = 'Justin') However, there are situations where
'* you may want the Where clause to include the OR statement between each set of statements. For example,
'* (strLastName = 'Smith') OR (strFirstName = 'Justin') In this case you need to tell this routine to use
'* OR rather than AND. Therefore, the first argument in this ParamArray should be " OR ".
'*
'* Control Examples:
'*
'* ListBox
'* -------
'* Visible ........ Yes
'* Enabled ........ Yes
'* Multi Select ... None, Simple, or Extended
'* Tag ............ Where=tblEmployee.lngDepartmentID,Number;
'*
'* TextBox
'* -------
'* Visible ........ Yes
'* Enabled ........ Yes
'* Tag ............ Where=tblEmployee.dteBirth,Date,>;
'*
'* Range
'* -----
'* Text Box (Begin Date Range: Name must end with _BeginR)
'* Name ...... txtHireDate_BeginR
'* Visible ... Yes
'* Enabled ... Yes
'* Tag ....... Where=tblEmployee.dteHire,Date;
'*
'* Text Box (End Date Range: Name must end with _EndR)
'* Name ...... txtHireDate_EndR
'* Visible ... Yes
'* Enabled ... Yes
'* Tag ....... (not used...function relies on tag property of BeginDateRange text box)
'*
'* Option Group
'* ------------
'* Visible ... Yes
'* Enabled ... Yes
'* Tag ....... Where=tblEmployee.lngID,Long,=,3;
'*
'* Check Boxes
'* -----------
'* Visible ... Yes
'* Enabled ... Yes
'* Tag ....... Where=tblEmployee.ysnActive,Boolean,=,True;
'*
'* Calling Example:
'*
'* Docmd.OpenReport "rptYourReport", acViewPreview, ,BuildWhere(Me)
'*
'* or strWhere = BuildWhere(Me)
'*
'* or Docmd.OpenReport "rptYourReport", acViewPreview, ,BuildWhere(Me, " OR ")
'*
'* or strWhere = BuildWhere(Me, " OR ")
'*
