Hi all,
we are using Forms Builder 6.6,
we create a form as shown bellow.

in the above form ELIGIBLE LEAVES and AVAILABLE LEAVES are TextField's. We gave the default values to the TextField's
My requirement is if any one apply for a leave based on the LEAVE TYPE the AVAILABLE LEAVES should be updated if the leave is approved.
Please help me out.
Thanks in advance,
Sampath A.
