Passing Parameters to CrystalReports

[complan]

While Not recLoad.EOF
iXValue = rs!XValue
iYValue = rs!YValue

rpt.AddToFieldDetails "CaseSheetName", iXValue,iYValue

rs.MoveNext
Wend

Problem:
"rpt.AddToFieldDetails "CaseSheetName", iXValue,iYValue"

Here, "casesheetName" all the record values are getting loaded, where as i want only one record value to be loaded at a time.

so, i want a statement like this:

"rpt.AddToFieldDetails rs!CaseSheetName, iXValue,iYValue"

(where casesheetname is the field name)

But, unfortunately it's not accepting this..

Please clarify.
