First I want to thank in advance anyone who takes the time to read this post. I am having a mental block. I need to filter a drop down <selection> based on the numeric value in a div. So if the value is positive I only show items with the word credit, if the value is negative I only show items with the word debit. Thanks again for the help.

@freginoldMar 28.2016 — If just using vanilla JS, you could use document.getElementById('divID').value to get the div's value, compare it to 0 to see if it's positive or negative, and use .match() to return instances of either 'credit' or 'debit' in the list/string.

Success!
