I am doing a project for my spanish class and "can I put that in a bag for you" is my title so I want to be sure I have it right. Any help would be appreciated! Thank you!

¿puedo poner eso en un bolso para usted?

Here's a great translation website:

AltaVista - Babel Fish Translation

Be careful with bable fish. If you want to know how wrong it can get stuff translate something form english to another language back to english:-

Hi this translation can be a bit dodgy
Hallo kann diese Übersetzung eine dodgy Spitze sein
Hello can be this translation one dodgy point

I'm afraid I can't speak spanish so can't help with the original question :(
