Try putting a [scale] tag in your template to view the range of scale
values that your map produces as you zoom in and out.  This will help
you in figuring the numbers to use as minscale and maxscale.

Also, if the scale value is not in the range that you expect it may be
because the UNITS at the top level of your map are not set properly. 
The UNITS parameter must correspond to the units used by the EXTENT in
your mapfile.
