Agreed.
I almost feel stupid. I solved my problem in the most elementary
manner...without js or any error checking.
There are three questions. The first asks if either $A or $B should be
set. The second asks if $A should be set, and the third asks if $B should
be set. Subsequent processing queried the values for $A and $B. This is
why $A and $B could concurrently be set.
I renamed all variables to $C, but give different values, e.g., if nether
$A or $B are set then $C == 0. If $A is set then $C == 1. If $B is set $C
== 2. Using radio buttons all named $C, it's not possible to concurrently
set $A and $B.
During data processing, I simply test the value of $C.
I wonder how I'll waste tomorrow. :-(
