Problem with Script Using New() to Create a #Vectorshape

Question

Hello,
I am having a problem integrating an existing movie script into a movie I am building and I can't figure out why.
The single movie script, developed by JC in 2004,  appears below. It works perfectly in a movie all by itself. But I need to integrate it into an existing movie in which other sprites and behaviors must coexist.
The problem I am seeing is that gMem is created with the new command (can see it in the message window using put gMem), but it will not allow attachment of gMem.regPoint, gMem.centerRegPoint, and so on. These all return errors.
I would also be open to another solution to the problem. What I need to do is create rectangles that represent a plan view of a rooftop on an underlying grid and then be able to drag and place other images on it (it is for training purposes, not a game).
I am using MX2004 on a PC. Any help, deeply appreciated.

    if member(i).type = #vectorShape then member(i).erase()

on getFreeChannel
  repeat with i = 1 to the lastChannel
    if sprite(i).member.type = #empty then
      aNum = i
      exit repeat

Sean,
Thank you. Changing gMem handler from #new to #_movie.newmember did the trick. I still have not found the behavior or movie script that contains the #new handler that created the problem. I was not aware of the #_movie.newmember handler. Seems that because it is specific to a new member added into a movie that it may be more useful than just using #new when adding new members is needed. Is that so? Does it have any downsides?
Once again, thanks for your answer. By the way, I think the script was originally a J Chunick script.
Regards,
Rod
