Run Time Error 13 when User Cancels

[dcrane37]

I'm a newbie in this forum and a newbie with VBA. I need some help and I don't know where else to turn. I inherited this piece of code from Word97.
The code for the most part functions, but there's an interesting quirk I can't figure out. If the user runs this macro and clicks on a file to open, the code executes perfectly. If the user presses the cancel button, then runs the macro again they receive the Run time Error 13 Data type mismatch error. I can't figure this out. Any ideas?

Thanks.
