Can't execute user defined function in Excel 2007

Hello friends

I use excel 2003 and my friends in my workplace uses excel 2007.
Recently I insert a module to use function for conversion of numbers to text.

I enable macros and keep security level low and make changes in trusted publishers to allow Visual basic projects.The module works fine in excel 2003.

When I try to keep the same settings in Excel 2007 , an error message appears and I could not apply the above user defined function in excel 2007.
I have enclosed the screenshot of error message.

I need help and guidance from the experts.
