$key_num always has the same value because you are always setting it to the same value. You are first setting it to the number of keys in %columns $key_nums = keys %columns;, and then you increment it by 1 $key_nums++;. You do this for every value in @discounts that has a value of 1?

It's completely unclear from your question what it is that you are actually trying to do....a written description of your requirement would probably clarify this.

Examine what is said, not who speaks.
1) When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2) The only way of discovering the limits of the possible is to venture a little way past them into the impossible
3) Any sufficiently advanced technology is indistinguishable from magic.
