first two letters of two fields ? k ..

use the split function. or store the fields value in an array and compare the first two letters in the array !!

Ok, I'm using a CRM Application and I have a Field call X wich have another dependent field called Y. The First dield must be field with a number form 20-80 and the second field with the two digit of the first one plus 4 more digits.
EX.
Field #1 : 21
Field #2: 210132

I need to validate the imput before store it into the DB. How can I store the fields value in an array and compare the first two letters in the array?

Many thanks
CP

Just grab hold of the field values using either document.getElementById('elementId') or document.forms['frmName'].elements['elementName'] , store it in variables and compare the characters at the first index of both the strings (make sure you use trim).
