How click on combo data to show into another

**raihan** · 04-02-2013, 01:08 PM

Hi,

I have created few combo box with few data in those. Please check my site raihans.co.uk. and log in as: dbuser, pass: passwd. Then hover on User Log In/Out, click DB Test.

What I am looking is: say,
if I click on 'one' in Combo1, in 2nd Combo it will show like: 11, 12, 13, 14, 15;
or if I click on 'two' in Combo1, in 2nd Combo it will show like: 21, 22, 23, 24, 25;

again if I click on say, '12' in 2nd Combo, in 3rd Combo, it will show like: 111, 112, 113, 114 and so on.
I have tried in some way, but can't sort it out.

Pls, help me, how I can do this?

Thanking you in advance.

Raihan
