[xmonad] view workspaces in Xmobar

[linuxham]

Hello, I am new to configuring Xmonad, and am trying to get Xmobar to 
show workspaces. I am using the Xmonad.hs from here:

https://xmonad.org/TUTORIAL.html

And my Xmobarrc is attached.

I am running Endeavor OS, with xmonad-git-0.17, and 
xmonad-contrib-git-0.17, and xmobar-get-0.36

When I boot into Xmonad, the Xmobar says "Updating", but doesn't show 
anything!

Thanks Ed

PS I read all of April, but didn't catch the fix!
