Hello, I've just begun using openlayers recently. I've managed to learn how to add markers etc. and thankfully, my code's working correctly.
I'm having some trouble adding popups though. I've been trying to go through the examples and figure out how OpenLayers functions so I can add popups correctly. Can someone please give me a step by step procedure of adding popups to markers (on clicking the marker, i want the popup).? I do get this error at times : "px is null" (using firebug). On looking at the OpenLayers.js file and tracing the error, it looks like px is null because the layer is not a baselayer. I've set my layer to base layer and I still can't display popups. It's because of my limited understanding of the internals of OpenLayers. :| Here's my current code to which I need to add popups. [1] The related sources etc are all here[2].
