@alien4u Nothing shows up until I press the "Update Vendor" button. I know what you mean though by the

N/ui/dialog

not waiting before it continues with the script. I've found that out with

saveRecord

script I was working on. So if we ignore the dialog part of the script and based on your code snippet I should be able to do a

record.load

and then I would have to use a

record.selectLine

so I can use

record.setCurrentSublistValue

.
