Ensuring Two Form Fields Have Identical Information

Form Fields with Un-Identical Information
|
|
To ensure that two form fields contain different instead of identical information, one change needs to be made in each JavaScript function.
Where you find
if(one == another) { return true; }
change it to
if(one != another) { return true; }
Changing "==" to "!=" causes the code to compare for inequality instead of comparing for equality.
Optionally, change the alert message and the JavaScript function name as appropriate for the changed code.
