nothing shows up! no image or error?

You may want to take a look at your extent.  

Do you really intend to show a primarily empty stretch of the northern
Atlantic Ocean (apologies to Canary Islanders...)?  

You are telling MapServer that your map area is contained within a box
from 50 deg. west longitude to 10 deg. west longitude and 20 to 90
degrees north latitude.  If the name of your mapfile relates to the
data, I am guessing that Richland County isn't in this box.  

Use ogrinfo or a desktop GIS app to look at the extent of your data.
Also, the extent needs to be in the units of the spatial reference
system that your data is in.

	Hi,

	 I am making my own map file.  It looks all right but when I
click the button it doesnt show an image or any kind of errors.  

	Here is my map code.
	#This is Richland County Map Server
	NAME "Richland"
	SIZE 100 100
	IMAGECOLOR 255 255 255
	IMAGETYPE JPEG
	SHAPEPATH "/home/mapdata/"
	EXTENT -50.00 20.00 -10.00 90.00
	WEB
	  TEMPLATE '/var/www/htdocs/richland.html'
	  IMAGEPATH '/var/www/htdocs/tmp'
	  IMAGEURL '/tmp/'
	END
	LAYER
	    NAME "Richland"
	    STATUS default
	    TYPE polygon
	    DATA "RICH_bndy"
	    CLASS
	       STYLE
	               COLOR 0 0 0
	       END
	    END
	END
	END

	here is my html code
	<html>
	<head><title>Richland County MapServer</title></head>
	<body>
	  <form method=post action="/cgi-bin/mapserv">
	    <input type="submit" value="Click Me"
	    <input type="hidden" name="map"
	              value="/home/mapdata/richland.map">
	    <input type="hidden" name="map_web_imagepath"
	              value="/var/www/htdocs/tmp/">

	  </form>
	  <table border="1" width="400" height="400">
	  <tr>
	  <td align="center" valign="top">
	  <IMG SRC="[img]" width="400" height="400" border="1">
	  </td>
	  </tr>
	  </table>
	</body>
	</html>

	 I really dont know whats could be wrong.  Maybe the extent of
it?  Can anyone help me?

	Thanks,
	Albert
