gbounds

Hi everyone,

I'm working on my 1st custom map and I can't seem to get the GBounds
correctly, because everytime I try and input it from the script on
Mapki, it is saying that I don't have maps for the zoom level, where I
made map tiles for that specific zoom level. I followed the map tile
directions correctly (using the onnyturf site for help too), so I'm a
bit confused.

Here's the limited region part of the code:

yourMapType.bounds = new GBounds(-135,66,-68,22);
yourMapType.getBounds=function(){return this.bounds}

is that correct for seeing the continental US at zoom level 13?

thanks in advance
