Trying to autofill two colums from one dropdown box please help

Hi All, I'm quite new to excel formulae and am trying to crate a new order request form for my workplace as I order ink cartridges very regular and have to manually type these up every time.
I have attached a example of where I have got up to where sheet 1 has my order request form which will calculate my costings but I'm trying to link column A & B to the second sheet (renamed items)
What I would like is to create a dropdown box in column A to select the code from column A on sheet 2 so that it auto fills the description in on column B from column B on sheet 2.
I can get the dropdown box for column A to work but can't figure out how to populate Column B from this.

Any help would be greatly appreciated.

Thanks

Hi Spencer & Fotis.
Thanks both of those work perfectly.
If I could just ask one more question, can this be dynamic so if I add more data to sheet 2 it becomes part of the dropdown choices (ie we get a new printer so need new toner types adding to the list)

Thanks again

Hi again, ignore the final question I've figured it out, but just wanted to say thanks again as this will save me a massive amount of time on day to day ink orders.

Thanks
Aaron
