Excel Export Macro fileformat Problem

[#1]

Hi,

I'm exporting from QV to Excel via a macro. I'm also doing some formatting.
Works absolutely fine. I use Office 2007.

If another user tries to open these excel files I'm getting an error that the format is not compatible.

Anyone an idea how I can fix this??
Thanks a lot.
Regards

Aloah
