Need a check on a script I've used for show/hide

I think I've found an easier way round this - there's a tick box associated with 'model4' and this has to be ticked manually, so I'll add a script to that to make the message visible/hidden.

@try67 and @Karl_Heinz_Kremer - I now know scripts do not trigger if data is merged. This will be very helpful going forward, so thank you.

A validation script is only triggered when a user enters information into the field. If you fill in data via a process that does not involve the user interface, the validation script is never triggered. One thing you can do is to create a document level script that is outside of a function scope. Such a script will be executed every time the document gets opened. That script would then loop over all fields that can potentially contain data and check if there is data entered. The first time you encounter a field that has data, you show the field on page 1, if you make it all the way through the list without finding data, you hide the field. 

Hi,

Curious as to what you mean by "Automated System"?

Where did you place the code?

Merging or importing data into a file doesn't trigger any of the scripts in it. If you're using a script to import the data then you can add a command to force calculations to happen, but if you're using the built-in Import Form Data command that's not possible. You can do it when the file is opened, or saved, though.
