Error in client scripting course - onSubmit script error: ReferenceError: validateFunctionDeclaration is not defined

[Daniel R1]

Hi, I'm doing the paris scripting course https://developer.servicenow.com/dev.do#!/learn/courses/paris/app_store_learnv2_scripting_paris_scri... and I'm on the client scripting module learning about the onLoad, onSubmit and other different functions, but I cannot activate the example scripts that I got from the needit application, I get the following error when I update or save any script:

onSubmit script error: ReferenceError: validateFunctionDeclaration is not defined:
function onSubmit() {
    var functionName = g_form.getValue("type");
    if (functionName == "")
       return true;

    return validateFunctionDeclaration("script", functionName);
}

But I only have 3 scripts 

and the onSubmit script only has this code 

What is going on? Am I doing something wrong?

take off the double quotes

.getValue('fieldName')

How am I supposed to do that when I don't even know where that script that is causing the error is located?

The client script generating the error appears to be a SNC platform script
/nav_to.do?uri=sys_script_client.do?sys_id=30d8ba710a0004df0c51c0c92601037b

I would set your 3 custom client scripts to inactive
test to confirm the issue is resolved
then activate them 1 at a time and test to validate each script.
Once you know which script is at fault it will be easier to diagnose the issue.

Yes! That's the script that's causing the problem, none of the scripts I mentioned are active, I tried disabling the script you  listed but I get the same error 

SSo what can I do to fix this? I cannot update or save any script 😕
