A strange problem...

I have a form with parent (header) and child (view) in a grid. Works just fine in VFP but not in .EXE...

Error message:

SELECT * FROM crsdata!empldtl WHERE empldtl.repno = mrepno
   ORDER BY empldtl.fiseff DESC, empldtl.sysdate DESC
   into cursor Viewcalv89
Error:   1732
Data type is invalid for this property.
Method: navrefresh
Line:    0

*note: mrepno was actually programmed as ?mrepno in the view designer; and in the form data environment NOLOAD was set to .T., mrepno gets the value from the parent

Why would it work just fine in VFP as stand-alone but not in .EXE...? All other forms, including views, work just fine.

TIA
