can't do math

[cowhead]

Rev apparently evaluates any non-number as an infinitely high number?
Anyway, your (Bill's) 'if' script is definitely evaluating a
non-number.  You can prove this by changing

"if word 3 of line x of varAllGroups > 100 then"

to

"if word 3 of line x of varAllGroups is not a number then"

good luck
