Save Fill in Fourm data into an array

hi everyone,

i have a fill in fourm the sale’s team fills out each day and i would like a way to have ‘history’. Meaning they can press a back button of some sort to go to the previous day. I would only want 2-5 days worth of data. The data consist of only strings and numbers. My though process was somehow putting all that data in a 2D array. Would an array accomplish what I want or is there another way to store this data?

thank you in advance.

if you need more information on the data or the fourm please let me know.
