Listen tilly,
Unbelievable! Everytime there's a conflict with the other scripts yours gets it right. Hat tip to you, tilly!
I must only use it when the others fail because of the time problem, but I'm sure it will do the work right.
It's gone now through 20.000 arrays and not a single problem.
Also, the decimal numbers in the values can only be .5, which I understand is fine for the script.
Thank you so much.
