Hi I am a complete newcomer to blender and am following this tutorial, where he says to alt+click to select an entire row or "edge loop". I have followed all instructions exactly up to this point (3 times to make sure!). Alt-click does nothing. Thank you for your help. p.s. If possible, please keep answers in simple layman's language. I see some similar posts about alt click and loop select but had trouble following since the explanations were too advanced. Thank you!

I also had difficulty following this portion of the tutorial initially, but I got it to work. Things to check:
1. Are you in "Edit Mode"? Otherwise you can't do anything with the mesh
2. Are you in "Vertex Select" mode?
3. Do you have a continuous loop present for your selection? (I'm assuming you're doing the tutorial series, in which case you should have a torus which meets this criterion)
If all of these things are present and you still can't loop select, I don't know what's wrong.
