Basically it's a form that uses post and when you click submit does simple calculations.
For form fields to get it to keep the values upon submit is no problem, I'm using this:
<input id="variable_a" type=text name="variable_a" wrap=virtual value="<?php echo $_POST["variable_a"]; ?>" size=3 maxlength=10>
If I didn't echo it, it would lose the value on submit.
BUT - I can't figure out on radio button how to do it (so it will show what was selected after submit). I need one radio button to have a value of "1" and the other to have a value of "2".
Can anyone advise me how to do this?
