[OpenLayers-Dev] Problem with popup in MapServer layer

[florencia.bujan]

Hi, 

I am from Uruguay and sorry because my english is very poor. 
I have a problem with a popup. I want to show a information from postgis
database (geodatabase) when the user mouse over a line in a mapserver layer
(in this case line layer). 

I am investigate a lot of days and I work with a lot of examples, but I
can't do that. 

This is possible? Can you help me?... 
I don't know if I am in the correct way but the last example is these (I'm
base on this example:
http://dev4.mapgears.com/bdga/options-by-zoom-and-highlight-bdga.html) 

Thanks a lot!! 
Regards, 
Florencia
