How to catch the selected value for second drop down list?

[wonder_gal]

I have 2 drop down lists here. Supposingly, upon the selection of the 2nd drop down list, I should be able to see textbox entry allowing user to update data being displayed at the bottom. But in my case here, i see no response upon the selection of "selType" which is my second drop down list.
but both also don't work. So any suggestion on how can I retrieve the 2nd drop down list' selected value? Anyone who know how pls kindly let me know. thanks alot...

I don't quite understand where your going with this one. Are you trying to populate a second dropdown dox dependant on what is selected in the first drop down box?

for example..... dropdown box 1 you can select fish, then in dropdown box 2 you want salmon, tuna, cod.

Is this what you need?
