IF FORMULAS

Hello,
I am trying to create a formula on one page that will allow me to enter an alpha code in one cell and will return the codes description in another cell. I have create another page with a range of alpha codes in column "A" and the code descriptions in column "B". For example: If I enter "e" in the code cell of the first page, I need the formula to look on the range page in colum "A" for the alpha code "e" and return the text/description next to that code in column "B".
Any help would be appreciated.
