What you say this token combination is intended to do, and how it's currently structured, seem to be almost completely different things.
If you just want to see the value of the ">Loop_Counter" variable, all you need is
{INT:>Loop_Counter}
If you have a loop that's counting up, and want to check how many iterations remain (these examples assume a loop counting from 1 to 10), that could look like
{EXP: 10 - {INT:>Loop_Counter}}
or, if you'd like count from 10 to 1 instead of from 9 to 0:
{EXP: 10 - ({INT:>Loop_Counter} -1)}
(you could just use 11 instead, and do away with the -1, if you prefer; use what's most readable to you)
What you have currently is a statement that will be evaluated, as indicated by the "=" operator.
That means the output of the "{EXP:}" token will only ever be 0 for false, which is the only possible output in this case as you're comparing a number to that same number minus one, which will logically never be equal, or 1 for true.
