Quick form question

[Anon]

I have created a test that uses php and mysql. The test has radio buttons and three questions per page. If the user doesn't answer all the questions a warning comes up to alert them. However if the user answers two out of the three questions I can't figure out a way to get php to print the two the user answered. They are always erased.

<?php print $variable ?> isn't working

I know you can use php to remember text box values but what about radio buttons?

thanks

Lets say you have this..

<INPUT TYPE=RADIO VALUE=YES NAME=question1>
<INPUT TYPE=RADIO VALUE=YES NAME=question2>
<INPUT TYPE=RADIO VALUE=YES NAME=question3>

just do this..

if($question1){
print "<INPUT TYPE=HIDDEN NAME=question1 VALUE='$question1'>You answered $question1<BR>";
}else{
print "<INPUT TYPE=RADIO VALUE=YES NAME=question1>";
}

if($question2){
print "<INPUT TYPE=HIDDEN NAME=question2 VALUE='$question2'>You answered $question2<BR>";
}else{
print "<INPUT TYPE=RADIO VALUE=YES NAME=question2>";
}

if($question3){
print "<INPUT TYPE=HIDDEN NAME=question3 VALUE='$question3'>You answered $question3<BR>";
}else{
print "<INPUT TYPE=RADIO VALUE=YES NAME=question3>";
}

I didn't include all the FORM and text you'd really have, but im sure you get the idea.
