But the problem is how can validate add up of both 3rd Party Transfer and Bill Payment can not exceed 10,000???

Thank You!!

Hmmm, not very helpful.

In any case, the scope of JavaScript is limited to a single page. You'll need to carry data from the first page to the second if you want cumulative validation.

P.S. Scriptlets in JSP? In 2011? Time to update.

Thanks for reply!

I think i can not manage carry data from first page.

I am new in jsp.

If you are new to JSP, it's important to use good practices right off the bat. That means never putting Java code or scriptlets in a JSP. That's very outdated and a poor practice.

Rather, learn JSTL and EL.
