Would be good to know what line causes the error...

>OK UTers, for those of you have might have worked with WinFax Pro before, below is a snippet of code that gets a "Function arguement value, type or count is invalid" error message. The real bogus part is that VB example that I have from the WinFax SDK works successfully. It is that example from which this snippet is created. I don't see the difference.
