Hi, C:
The combo box wizard would do this for you if it's turned on when you drag the control to the form.
However, you can do this:
Bind your combo box to the field you want to save. Select the property sheet for the combo box and select the appropriate control from the box on the first row (Control source) of the data page.
In Row source type you can use "Table/Query" or you can type in a "Value list".
If your combo box has three columns, myField1, myField2, and myField3, then in the property sheet for your combo box, Format > Number of Columns, put 3. Format > Column widths, put "0.5;0.5;0.5". That will give you 1/2 inch for each column. Adjust to what you want. in Format > Total column widths put 1.5" or whatever; or leave it at auto (I never do, don't know why not).
In Properties > Data > Bound column, put the number of the column you want to bind to your table or query: it might be column 1, 2 or 3, depending upon which column holds the data for the bound field. (Remember, if you move this to code in a form module, column count starts at 0, not 1.)
You can also populate other controls on your form with columns in your combo box. If you want to do this, I'll post some code here you can put in the form module.
I hope this has been helpful. If I've missed the point, let me know. If I haven't been explicit enough let me know. I'm really busy on weekends, but by late Sunday afternoon I can answer any other questions. Access 2000 Help is really good for things like this.
Cheers.
