about security settings for macros

Hi guys ,
Im a little unfamiliar with VBA Excel , hope you can take a look at this:


Whenever I try to run a macro with VBA Excel I get this error :
The macros in this project are disabled. Please refer to the online help or documentation of the host application to determine how to enable macros .

I allready changed my Securtiy settings for macros to the lowest level and selected trust all for trusted sources , but I still cant run macros.


btw Im using Microsoft Excell 2003
much thanks.
