Try something like this:

With
Data list in A1:E10
A2:A10 contains codes
B1:E1 contains sizes

F1: (a code to lookup)
G1: (a size to lookup)

This formula finds the code value of F1 in A1:A10 and returns the
corresponding value under the column headed by the size value in G1
H1: =VLOOKUP(F1,$A$1:$E$10,MATCH(G1,B1:$A$1:$E$1,0),0)

Does that help?

I have a table of data that I would like to use both the hlookup and vlookup
function at the same time to retrieve data. Column A is a listing of codes,
and my column headings consists of 4 sizes. How can I write a formula using
both a vlookup and hlookup at the same time? For example, in a spreadsheet,
if someone enters a code in one cell and a size in the adjouning cell, how
can the formula return correct value from the table of data?

Thank you
