Hi Carla,
I am currently out of columns on my Excel Spreadsheet and need more!!
You will have to wait for the release of Excel 12, which will have
16384 columns. Until then (fall next year), you are stuck with 255
columns and will have to find a way to reorganise your data. Maybe
transposing rows and columns is the way to go after all?
