Any ideas to why this is happening? I don't have any scripts deployed here. https://imgur.com/a/2WfnvwQ . I'm trying to pick a receiving location for that line item but for some reason it opens up that other list.

try checking on the console. it might not be a script error but NetSuite fails to load the resource. You may try to check out the profiler functionality to get to the JS function of NetSuite that is having the issue

I appreciate your reply. When clicking on the receive location line item field I get this error: "Cannot read property 'value' of undefined" https://imgur.com/MJa3JN1

Yeah. You might need to report that one to Support. It does not seem to be a script related issue

Cool. Thank you!
