How to hide button button on state change

[ritaaudi]

Hi: I want to be able to hide the Close Complete button on the RITM form when the state changes to Closed incomplete. I tried this but it didn't work:

I don't get the alert 2 popup. Any idea? Thank you!

If the script works, then the only change i would recommend is changing the client script to a OnChange Client script with field name as state, which will trigger the client script. onLoad client script only runs when the form load.

Sorry I made it onload for easy testing. Script is not working: " $$ is not a function function () { [native code] }"

Looks like you can utilize a UI policy for this. Can you refer the solution in below thread.

I tried UI Policy too but it is also erroring on the $$

Thanks
