Run-time error '28' Out of stack space - Code alteration help required!

Hi All,

I have recently upgraded to office 2007, not one of my best choices at this moment in time however, i wonder if someone could help..

I created a spreadsheet in excel 2003 and had no issues with the code i created. Please see attached exert from sheet, when i try to run it in 2007 i get the error code '28' and i have no idea to solve this, i have hunted around the forum but found nothing applicable to my sheet.

If anyone could help out it would be greatly appreciated.

Thanks in advance,

Paul
