WMS through ArcGIS Viewer for Flex 3.1 doesn't work

Sorry, I'm new to the flex viewer. I have been having a lot of problems getting our WMS hooked up to our Flex Viewer. Here is where our WMS is located online:

http://imagery.carbon.utah.gov/latlonghistorical

And here is the web map:

http://maps.carbon.utah.gov/flexviewer/trails/

If you go to the web map, you'll see in the layers widget, it recognizes my WMS layer (CC_WMS) but it doesn't show up. Right above my CC_WMS layer, you'll also see a NRCan layer and if you zoom out to where you can see Canada it show up just fine.

I've gone to my configuration file within the webmap, inserted my WMS information exactly the same as the NRCan layer, that works, and my CC_WMS layer still doesn't work. Below is how I've set up my config.xml file:

<operationallayers>

I've tried putting the WMS in as a basemap layer and as an operational layer. Not sure where it should go as well.

Any help would be great thanks!
