The following script shows how to increment the custom (L:Variable,unit) value by 1 on each "click". The number preceeding the modulo operator (%) is the reset point (highcount + 1), at which point the variable will reset back to zero!

'''NOTE: this technique works for integers only. Fractional increment/decrement should use other methods.'''

 0 + click = 1; 1 mod 5 = 1
 1 + click = 2; 2 mod 5 = 2
 2 + click = 3; 3 mod 5 = 3
 3 + click = 4; 4 mod 5 = 4
 4 + click = 5; 5 mod 5 = 0
