Thanks, Moshe! I feel like I’m getting closer.
I tried exactly as you explained, and that populated the Project field with the Project’s record ID. Then I tried to also include the parameter for the project name (CF00NU0000004jAzH). Everything looked good, but I got an invalid reference to project id error on save.
Then I tried with just the parameter for the project name, and everything looked GREAT… until seconds later when the prepopulated project name field cleared itself of any text.
Maybe I am really close to getting it without javascript? Or maybe it is easier with javascript? In any case, I am very grateful for your help!
