Hi there,
I'm a relative newbie when it comes to scripting in=

d to numbers together to reach an answer. I've effected some coding however=

What loops? I don't see any loops in there at all. I see two co= nditionals ("unless question =3D=3D 20" and "unless user_ans= wer =3D=3D correct_answer") but no loops.

That might be a clue.
