Me and my classmates are working on a project and we ran into some trouble. We are making an online storage system and for the storage we need a map. We decided to do it with a table (letters from A-Z are rows, numbers from 1-10 are collumns) that the user can check. So the user can store something in sector A-1, Z-8 etc.
We would like to check every sector with a loop and if a sector is still free the value in the table cell will be "FREE", otherwise "FULL".
