I accidentally changed the link to the full sized category item and don't know how to fix it

I was poking around in the back-end today and accidentally changed something and now I don't know what I changed.  I normally have my articles set up so that when you click on the article image (coin), it should take you to the coin's extra info page and allow you to click on the image to see a larger more detailed image of the coin.  Now when I click on the image article, it takes me to a page that shows me nothing except the JComments input.  Would someone be able to help me fix this so when I click on the link it goes back to what it was before?  None of my detailed pages are showing up anymore.

Never mind, I found it. In the Article type, under Layout, the Default Item Layout wasn't set to Default. It is now, and works fine now.

perfect thanks for share your solution
