EDIT: Also, I have the following Command setup:
*Keyboard: A is down
-Array: Set Size to (Array.Width+1,0,0)
*System: Every tick
-Text: Set text to (Array.Width)
But when I press A the size of the array never increases it just remains at zero. I even tried adding on the start of a layout to change the array size to (2,0,0) and the text still says that the array width is 0.
