// JavaScript Document

/*Read the following before using these script
1.First of all you will have to name your form with names like form1, form2, form3 etc.
2.While calling the function validate() on submit remember to pass form name as first value and then name
  of variables that you wish to validate.
3.If there are emailfield and numeric fields then you can make use of validateEmail() and validateNumber() functions
  For using both the functions you will need to make change within customScript() function and call both the functions
  from customScript() function by passing formName first and respective fieldNames
4. Still if any confusion you can contact me @ sunil@indianic.com
