[maplab-users] Re: Yet troubles in MapBrowser and IExplorer previews

[Daniel Morissette]

Hi Expander,

I had a look at your screenshots and the first thing I would suggest
would be to remove the MINSCALE and MAXSCALE in the web object,
everything else seems OK after a quick check.  The MINSCALE/MAXSCALE
values control the scale range at which your map will return something. 
Outside that range nothing will be returned, and since the values you
entered for MINSCALE/MAXSCALE don't seem valid to me at first then I
suspect that this is what the problem is.

BTW, attaching a copy of your .map file in plain text would have done
the trick too and would have saved you from having to create all those
screenshots.
