I guessing you mean that you want to have a set of radio buttons and have the value (the number) of the selected radio passed when the form is submitted. If so, here's how to do it. <FORM METHOD=POST ACTION="http://Some url"> <INPUT TYPE="radio" NAME="myRadios" VALUE="1"> radio1<BR> <INPUT TYPE="radio" NAME="myRadios" VALUE="2"> radio2<BR> <INPUT TYPE="radio" NAME="myRadios" VALUE="3"> radio3<BR> <INPUT TYPE="submit"> </FORM> Now, because the radio buttons have the same name they will act like radio buttons and not checkboxes (i.e. you will only be able to select one). When one is selected and the form is posted then the name "myRadios" will have the value of the selected radio button (1, 2, or 3 in this case). So if you ask for the value of "myRadios" you will get the value of the one selected. You can set one of them as a default by doing this. <INPUT TYPE="radio" NAME="myRadios" VALUE="1" CHECKED> radio1<BR> I hope this helps. Sean
