One more piece of info:
I don't know if it's important or not, but this form is being called modally from another form. When the Type Mismatch error occurs, the program's 'debug line' hangs on the modal call in the startup form, not in the actual form where the flexgrids are:
VB Code:
  1. Private Sub Command1_Click()
  2. [HL]formRateSheet.Show , vbModal[/HL]
  3. End Sub
