Using a radio button to make a conditional statement in a javascript:
IF "convert feet to inches then multiply field by 12" ELSE "multiply field by 304.80"
Number of feet:

Here is the code:
<script type="text/javascript"> function check(rb1) { document.form_1.rb1.value=rb1 if(rb1<2) { inches=document.form_1.GapSpeedGroup.value answer=inches*12 alert(answer) } else { mm=document.form_1.GapSpeedGroup.value answer=mm*304.80 alert(answer) } } </script> <form name="form_1"> Number of feet: <input type="TEXT" name="GapSpeedGroup" value="21.58">> <br> <input type="radio" name="rb1" onclick="check(this.value)" value="1"> convert to inches <input type="radio" name="rb1" onclick="check(this.value)" value="2"> convert to millimeters </form>
