Been messing with this for at least an hour and I cannot for the life of me get the script output. I've shortened the number to a "int". I've tried casting to int. I've tried different variations of the output. Made sure to include unique name in the output. Tried to just write the output from my FreeSpaceCheck function.. Nothing work..... please assist
