How to wait until process exit if process number is not known

[CREvans]

How would I use that vbld_FindProcess function? I tried putting that into the wait step in the Process ID(s)" area and it failed, and when trying to put it into a vbscript piece as follows:

id = vbld_FindProcess("WINWORD")

or

id = vbld_FindProcess("WINWORD.EXE")

both gave a type mismatch error.

If I put it in brackets (i.e. id=[vbld_FindProcess("WINWORD")] it gave a null return, even though I have winword running. (same if I put it as WINWORD.EXE)
