problem in javascript validation

[Prakash Mani - Attur]

I have validated the form using commons-validator 1.0 using <html:javascript> tag.. wheni use that i got an error "undefined mehtod userForm_IntegerValidations()"...then i gone through ranch forums and changed the commons-validator 1.0 to commons-validator 1.2.0.. now i am getting "object expected error" in the validateInteger(form) method in the line no 3 and 5..

var bValid = true;
        var focusField = null;
        var i = 0;
        var fields = new Array();
 
        oInteger = eval('new ' + retrieveFormName(form) +  '_IntegerValidations()'); 

Please tell me what i have to do.. i am sitting in this since from the morning..
