triple combo into frames

[ztheged]

G'dday folks!

Would like to ask for some help regarding two issues with a triple combo script from javascriptkit.com.

First of all, a matter which I have read about already in this forum, but did not become quite clear to me, and thus didnt work:
- how can I make the combo script have its links point into a frame, or in my case an Iframe (!). I tried the coding

}

function redirect2(z){
parent.chartsloader.location=temp1[z].value
}

where the iFrame's name is "chartsloader" but got an error on trying to access a link.

Second question is how to make the triple combo work so thata user would be able to simply click the 3rd combo and see the complete list or airports, not have to first select the region and country. (Yea, you guessed it! It is intended to create categories for chart downloading, like 'Select Region' > 'Select Country' > 'Select airport'. Is this possible without the need for server side scripting?

Thanks in advance for any help!

Cheers

PS-- Maybe would have been better to post the full code as well... :rolleyes: better late then never
