How do i go about knowing the form element names for two text boxes in order to pass them both to the javascript function? I realise that parameter 1 is infact a reference to the form text box which the rule is linked to. my javascript knowledge currently stinks :-/ Has anybody already successfully used a javscript function to check if two text boxes are equal as part of the validation?
