[OpenLayers-Users] Layer.MapServer.Untiled() Help

[Stephen Woodbridge]

Christopher,

Thank you that did it. I had stupid cut and paste errors. Anyway, 
attached it a tarball with a working MapServer.Untiled.js and an example 
file. Please feel free to add these to the source tree. I pass whatever 
rights you need with respect to these files to incorporate them.

Thank you for all your efforts and all your support.

-Steve
