Hi I am working on scripts that work in DIAdem 8.10 but when i run them in DIAdem 9.0 they seem to give me an error. The error is Object Type Unknown. When i go back to the script editor it points out that "call GraphObjChnClear(PicObj(L1))" is an error. It isn't just for this one script either. It does this for other scripts to that are almost the same but instead of picobj its a txtobj. Thanks for your help.
