Hey Jim,
The & operator is a logic operator. For concatenating strings, you should use the + operator.
Also, you aren’t retrieving the dropdown value correctly. It should take the form:
$w(“#dropdown”).value
This is closer to what you want:
wixLocation.to(url1 + space + Events + space + $w("#dropdown2").value + space + $w("#dropdown1").value);
I have no way of knowing if you have other problems, but at least from the code segment that you posted this is what I see.
I hope this helps,
Yisrael
