Hey clarkitsn, Your name of "pyschofish94" is not your actual Steam ID. It appears that you're trying to put in a username, which is not what is needed to donate. You can get your Steam ID by going to http://steamidfinder.com/ and inputting the URL to your Steam Profile in the box. It'll then give you the Steam ID needed. It should look something along the lines of STEAM_0:0:00000000 (with different numbers). You'll want to put this in as your Steam ID instead. It should work after that. Please let me know if you have any more questions or if any other troubles should arise, I'd be more than happy to help you out. Thanks for donating! We appreciate it.
Alternatively, you can just go into your console and type "status" and your STEAM ID will appear directly to the right, as shown here:
