@John Rosa i don’t think there’s a (non-DOM manipulation) way to set the ‘mandatory’ flag on a field in a client script. you could do it in

beforeLoad

on a client user event script. but you can use

saveRecord

in a client event to check a field’s value and prevent the ‘save’ from happening.

I could use a UserEvent script, but I need to pass a value form the client script (The value is collected from the url) to the user event script

but the value doesn’t go in the field you’d like to make mandatory?

No, ideally I'd like to use the presence of the value to make fields mandatory or not

user event beforeLoad has access to the url via scriptContext.request

REally?

yup

That's good news, and easier than anything else
