Gusset on round needles

I am making my first pair of socks using one round needle.
After ripping out the first 4 rows of the gusset, I lost my markers and don’t know where to put them to start the gusset again. Am I making sense?

Hmmm, could you please explain in a little more detail, and maybe post a pic, so we can see what’s happening? :thumbsup:
