iframe snippet embed issue

iframe snippet embed issue

Hi

We have 4 separate applications which have worked perfectly for several months.  The applications are exposed within an iframe with form and view snippets.

Suddenly all 4 applications come up with the following error message.

Error details:

Error occured while executing on user input script.

Unable to update variable

Error occured. An email has been sent to support with snippet details and access to one of the applications concerned.  The applications are currently unusable. The coding has not been changed, so something has changed at the zoho end to casue this issue.  Is anyone else getting this issue with snippets embedded within an iframe?
