Subject: RE: **UPDATE** Arrange sequential selections into ranges how to???
Maybe I've made it more difficult than it has to be.
Ignore the <select> stuff.
Let's say I have a variable being passed to my action page that contains the
following (this can vary):
var1 = "1,2,3,4,5,6,10,11,12,13,14,20,25,30,31,32,33,50"
How can I arrange the above variable into a range. Meaning...how can I take
any input from the variable and basically create a new varaible with the
following:
var2 = "1-14,20,25,30-33,50"
Notice that if the numbers run consequtively they are "grouped" starting
with first then last separated by a hyphen.
Is this possible? I know what I want to do but its how to implement it.
