ValueList just lists some values to use as calculated dimension
eg valuelist('a','b',c') will list values a, b and c.
ValueLoop will generate a series of numbers starting with the first parameter, ending with 2nd and having the 3rd as step.
ValueLoop(1,9,2) will generate values 1, 3, 5, 7, 9
ValueLoop(1,6,1) will generate values 1, 2, 3, 4, 5, 6
valuelist(1,2,3,4,5,6) is equivalent to ValueLoop(1,6,1)
