When I do field.removeSelectOption in the console it works, but when I try doing it from a field changed or post sourcing it doesn't

Is the field in a subtab?

Nope

It's a line column?

No. A custom field for list/record with sourced info

Is the custom field a field created in UE / Suitelet with a custpage prefix?

no

It's beyond what I know, but if it isn't a field created with custpage, removeSelectOption is unlikely to work Usually you'd go with a (fake) field or even a field via css and apply it to the real field if that's your final intention

But why would it work in the browser console?

you could do the same with a jQuery DOM hack, I think what you're doing in the console after the page has loaded (after pageInit etc) thats what youre doing

I don't mean page init. I am opening the chrome browser, loading the Netsuite modules, getting the currentRecord, getting the field, and trying to remove some of the options

If I understand you correctly, you're running code in the console, and you dont understand why the same code doesn't work pageInit?

Not Page Init. post sourcing and field changed

When it works, its from console?

Yes. In the console it works, in the script, it doesn;t

Just to confirm it's not a sublist field (transaction columns etc)? custcol_x

Correct

And when you load the page you can see the field immediately? And you're trying to manipulate it?

Okay. Thank you
