Script: Copy paste values from a Lookup field to a Multi-select field on same table

[Ann_Yeom]

Hi,

Looking for some scripting help. I am manually copy and pasting values from a Lookup field to a Multi-select field on the same table and want to know if there is a way to create a script that could do this process for me. 

Example below:

Want to copy the teams in the "Lookup of Teams" field and paste it into the "Manual Copy Paste (multi-select). 

Any suggestions appreciated! Thank you.

Yeah totally doable.  If you're going to be running this script via an automation, why not just use an "Update record" action to accomplish this though?  Here's a base with said automation set up

Best of luck with the script either way
