I have used macro to generate report between two Dates (From - To), it works on some PCs well but on some PCs generates error...see attachment
Could SomeOne help me?

I would suggest using a Dialog Box and refer back to the Start and End on the Report Query - I got really annoyed with Dates, this method damn well works!

[Client Sale Date] Between [Forms]![Sales Dialogue Reports]![Start] And [Forms]![Sales Dialogue Reports]![End]

The error message in question seems to refer to a problem that has to do with something OTHER than dates but rather to code trying to either set something either visible or invisible.
