Regarding changes to Javascript in Quickbase

Hi Everyone,

I am facing issue in injecting my custom code page. By reading  all the docs, I came across that in order to inject your custom code you have to  make a field and insert your custom page as follows : ""&[iol] & "Formula_Save_Proposal.js" & [/iol]&"".

Earlier it was working fine and was getting saved , but now when i am trying to save this field it is giving  error as shown in image attached for your reference.Could you please help me to find a solution for same.
