Script needs to wait for a nested iframe to be built before contnuing

[MuffinMan]

I think I am very close to having my script working, but I need a little help.  I am trying to screen scrape a web-based application we use at work, and I have found that it uses nested iframes to display its information.  When viewing client's data, a new frame is created, a "Demog" frame.  If I start the script with a clients info pulled up the script works fine.  If I switch from one client to the next, everything works fine.  If I go back to the main screen (which deletes the "Demog" iframe) or start the script before the Demog iframe is created, the script will break.

I really just need this script to do nothing until it finds that particular Demog frame and then scrape the client's info and fire a function based on the acct#.

Below is the code I am using and the error I am getting with debug on.  Any and all help is appeciated.

Pertinent output from debugger:

EDIT:  OK, I finally figured this out.  I updated my Autoit and IE.au3 to their latest versions and now the script works fine with no modifications.  Now I feel bad for not checking this before posting.

EDIT2:  Actually the latest code was giving me different problems, but was still erroring out around that last frame getting created/destroyed by the program  But I finally got around the issue by using a _IEFrameGetCollection loop to count the number of frames before I start looking for the correct frame.
