Request.Form -- Multiple Select -- How?

Question

Hello,

I have a multiple select list in a form. I want to get the items in that list. I have tried to get it like I get input text for example, with Request.Form("blabla"). But Request.Form("MultipleSelectList"), Gives me nothing.
How do I get the items in the multiple select list in the form? I guess it is pretty simple.

Thank you!
