I figured it out...

Instead of programming a separate .html file for the signature and the program to capture, I opted to go with a sendkey method

Here's my code...

'Goes to the end of the current email (so signature appears at the bottom)
SendKeys "{PGDN}", True

'Goes to the insert tab in the toolbar
SendKeys "%i"

'Selects the signature
SendKeys "s"

'Press enter to insert the signature
SendKeys "~"


Hope this helps everyone...


Thanks!
