you have an example in the scriptaculous demo... CSS highlight in the 
ajax tab...
SUEvaluator is like an updater except it injects a javascript chunk in 
the pasge if I remember well...

your problem is because isFormValid is always set to false ?

maybe after each form input, you need to make a SURequest so as to 
change this...
