Hi Gary:

That did the trick, using CLng took care of the "data type mismatch" within my DLL.

BTW, did you purchase any books that were helpful in using COM DLL's within a ASP? Any books on tricks of the trade?

Thanks a lot!!

Regards,

>We come across this same problem in VB COM components. Remember that all variables in VBScript are Variants so their types can get whacked when passing them as parameters. Try wrapping your variables in the appropriate typecasting function. In your case try CLng(FirstNumber) and CLng(SecondNumber).
