Thanks, Scott
Just loop thru the selected values

$('#DispSegmentList option:selected').each(function() {
//do whatever here for each selected value.

Maybe I am missing something?

my options values are "4,8630"  the first digit is the segment and the second digit is the industry

I need to set those field like this.

SelectedSeg = '4,5'
SelectedIndustry = '8630,3710'

so I can do the filter in the filterIndustry.cfm
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Normally I would use the data prop for the custom data attribute but it doesn't seem to work in this scenario

Hold off on this...
$('#DispIndustryList option:selected').each(function() {
    vals = $(this).val()
    SelectedSeg+= "," + vals[0]
    SelectedIndustry += "," + vals[1]
SelectedIndustry =SelectedIndustry .substring(1)
