hi ...

you may break the loop when you have an alert ... so put a

break;

after the alert-statement (line13)

kind regards

Cheers

Now I only get one message, however it still appears even if the last one is selected.

Do I have to ditch the loop and go for an "if / else if / else if / else" statement?

What will give the best result?

heya ....

sorry i overlooked that ;)

use the following:

Expand|Select|Wrap|Line Numbers

 
var show_alert = true;
 
for(j = 0; j < 4; j++) {

    if (document.fmOrder.whichSearch[j].checked == true) {

        show_alert = false;

        break;

    }

}
 
if (show_alert) {

    alert("Which search engine did you use?");

}

kind regards
