Automating excel

Im using OLE Automation to create an Excel instance and fill it with data in Visual Basic 6.0. This works just fine for most users. But one user has problems with filling the data. The instance is created and it seems to be working but the sheet comes up empty.

I was wondering if there are any settings in excel that prohibits the actual insertion? Cause the user has same version on both OS and Office as the users that successfully fills the sheet.

Or does anybody have a clue whats causing this.

There's probably an error, but since your error handler just quits without saying anything, you're not getting any information about that... add something useful to your error handler, such as a MsgBox that reports the error number and description, and once you know that we can start looking at how to fix it.
