Is a raise allowed here? Interesting hand scenario

[Torello]

That's completely retarded, assuming you posted the action correctly. You limped and then got raised, you certainly have action open and can reraise the guy who made it $15. The guy who's action is closed is the $15 raiser, if you just call he can't repump it, he can only call the extra $5. But if anyone told you that you can't reraise, they either completely misunderstood the action, or need to be shot.
