Column and Row lookup? Matrics retrieval

[jt76]

I have say a 26 by 26 grid of info and the row 1 is filled with values A-Z and column A is numbered from 1-26. How do I write a function that will search Range A-Z(Row 1) and then search range 1-26 (Col A) and when it finds the two values if will return the value in the cell they intersect?

ex.
given a 3x3 grid. top row of cells are filled with A, B, C and first calumn is filled with 1,2,3. I want a function that will return the value in (B,2).

Thanks.
