Newby Multidimensional Array Search question

Question

Hello, I have an array with two dimensions, G/L Account number and Cost Center. There are about 300 entries in the array. I want to create a function (class) and pass in a G/L account number and have it return the associated Cost Center. The Array.Search method won't work with a multidimensional array. Anybody care to offer me a direction? Thx. Andy Jacobs
