In the VBA editor, select Tools, References. If you have a reference to the
Microsoft Office Object Library, uncheck it if you can. Then see if the
module will compile. If you get undefined variables for vb constants,
replace them with their numeric values.

Of a virus problem I had to reinstall my windows xp and office xp.
And I faced this highlighted error
" Application defined or object defined error "
No need to add this was a smoothly working vba code before.

Worksheets("compare1").Range("a2:iv10000").ClearCo ntents

Any idea ? Thank you.
