Setup an Online Customer form, added a simple js file with the entry points as per the image, simple alert / console.log but see neither on pageInit. Any ideas? I have set the file to available offline in case that's the issue

The custom form script on an online form isn’t like the ones for internal NetSuite forms. It’s just a vanilla javascript file.

what does the file record for the client script look like'

@jen I hear you, I found it did not respect the fact it was SS2.0 if I did not structure it as indicated. A colleague tried to do the same but with SS1.0 and that works... interested to know if you've done it with SS2 and what that file looked like

Our only normal online forms just use boring regular JS, not even really SS1 or SS2 at all. Most of our forms are actually created with Suitelets as they are a bit more complex than what can be achieved with the NetSuite online form tool.
