Compatibillity issues 2003 v 2007

[twinpowr]

Hi guys,

I am having problems with two vba lines that work okay at home where i am using 2007. but when i try and run the code in 2003 which i use at work i get a "Can't find project or library"

The lines i am having difficulty with are

If Trim(FindString) <> "" Then

and this line

Data(Dn, Ac) = Format(Data(Dn, Ac), "dd/mm/yy")

Which library do i need to install, and can i do this programatically at workbook open

Any help would be greatly appreceiated.

Ally.
