Multiple Dropdown Select Boxes?

I'm populating a couple of dropdown boxes from an xml file, but can't get them working independently. As you can seehtmwhen you select an item from the first select box (a polyline), itdisplays the corresponding item from the other box (a polygon), too.I found this answer on the google maps forum:"Don't know of an example, but building two select boxes isn'tdifficult: pass into your createMarker() function the relevant flag,and add the data to one of two variables (instead of everything beingadded to select_html as now).You shouldn't need two handleSelected() functions -- both select listscan use the same function because each select box passes itself("this") into the function."which is what I thought I did (making sel_html and select_html) butmaybe the two variables being discussed here are different ones?cross-posted on the google maps forum here and here but not answered.
