[OpenLayers-Users] Update wms filter

[abolinhas]

Hi, 

This is my function:


I want that every time that I change the values of my select box, uptade the
filter and not create a new one.

Eg:
I have 3 layer or orverlayer but every time that I change the value in
select box a new layer or overlayer are created.

How can I dos this ?
