Referencing a cell address from another cell 1

[SellOut]

Hello,

I want to show in one cell the value of another cell which is based on a number and a letter in another two cells.

Something like:
=[cellA1][cellB2]

Where cell A1 holds a letter refering to the column and cell B2 holds a number refering to the row.

Thanks for any help!

Try

=INDIRECT(B2 & C2)

Where B2 and C2 are where you have the letter and number stored
