I was able to invoke csv files and concatenate them to a JMP table. I added some editing (modify column names, add column names, etc). I want to invoke another user defined csv file as another jmp table and extract information from that to add to the first concatenated JMP table

[#1]

Please see my script so far. At the end of the script, I want to open another csv file into a jmp table and extract columns into the originally created jmp table from the first invocation.

You can use Pick File() to let user select a file and after that you might be able to use Update to add the new information to your table. Do the update first interactively in JMP and then get the script created by JMP
