Problem with standard win dll

I have a problem. I can't get custom actions to work. that are called from a standard windows dll. My dll was built with MSVC 6.0 and it should work fine. I used the custom action wizard to link in the function. Below is some of my code.

void __stdcall Box(void){
MessageBox(NULL,"BOXTEXT", "BOXCAPTION",MB_APPLMODAL);
}
UINT __stdcall AnotherBox(ULONG value){
MessageBox(NULL,"BOXTEXT", "BOXCAPTION",MB_APPLMODAL);
return 0;
}

I always get an error message like this when I try to build the project:
** Error -3705: Error building CustomAction table

Some options in the custom action wizard:
In-Script Execution: Immediate Execution
Executiion Scheduling: Always Execute

The funny thing is that I get the same message when trying to compile someone else's example code
