Here's my problem: I have two simple radio button options "Radians" and "Degrees" to pass to a Processor Page to dynamically populate cells in a Trig calculation table. So, I got the trig calculations working (give or take to rounding I need to apply ). <b>What I can't figure out is how to make the data in the first column of the table show degrees in increments of 15 when I click the "degree" button or to show "Radians" in the same increments when I click "Radians".</b> Note: the Radian numbers are really a set of image files numbered 0.gif, 15.gif, etc. I actually have that working okay. I just can't figure out how to change the column data based on what radio option is chosen. I have correctly coded the column header correctly to show either Radians or Degrees. Be advised I am using a "for" loop. I assumed an IF/Else statement would work, but it's not.
Here is condensed code from form page:
Here is code from PhP "Processor Page. Variables to note: $trigstuff is the variable containing the $_POST data from the form page.
$counter is the counter used in the "for" loop.
There are other variables I used for the calculations for the other columns, but those don't apply to the first column.

Thanks in advance for any and all assistance.
