/*
    This is a generic code to validate any form.  To use this the following has to be on the form
    1) The form field must have a id and name and it is the first variable in the validate javascript function
       i.e. <form id="frmMain" name="frmMain" action="formprocess.php" method="POST">
    2) All variables must have and id set and the field name must have an id tag that is the same with a suffix of "name"
       i.e. <tr><td id="EMAILname">Email:</td><td><input type="text" name= "EMAIL" id= "EMAIL" value=""></td></tr>
    3) Textfields and textareas can have extra checks done, there is three possible ones, to do this create an
       array and add the field name and the type of check you want.   Key of array is id of field and value is type
       of check to do:  i.e.
           var variables = new Array()
           variables["ZIPPOSTAL"]="PostalCode";    -- postal code check
           variables["EMAIL"]="Email";   -- email field check
           variables["HPHONE"]="Numeric";   -- numeric check
    4) Checkboxes are not validated unless added to the variable array, in checkbox case, key is variable name and value is checkbox
       i.e.     variables["attr_chkInterests[]"]="Checkbox";   -- numeric check
    5)  To make fields not be check, add them to the optional array
            var optional = new Array();
            optional["prop_1036"]="prop_1036";
    6) To get the validation to work, add the validation function to the submit button
       i.e. <input type="submit" name="submit" value="submit" onclick="return validate('frmMain',variables,optional)">
