I am trying to store values into a array of type long but I keep
getting the following error:
subscript range values of the form low:high must be >= 0, < size, with
low <= high: ROIPIXELS.
The weird thing about it is when I set a breakpoint and step through
the code it doesn't throw the error anymore. Also, if instead I don't
use numClicks as the index and hardcode a 0 or 1 or 2...etc the code
works as well!!!

HELP!!!!!!!!!

roiPixels = LONARR(5,25)
numClicks = 1

WHILE(!mouse.button NE 4) DO BEGIN
CURSOR, xi, yi, /DEVICE
IF(!mouse.button EQ 1) THEN BEGIN
x = LINDGEN(5*5) MOD 5 + xi
y = LINDGEN(5*5) / 5 + yi
roiPixels[numClicks,*] = x + y * 1024
numClicks++
ENDIF
ENDWHILE
