Need help with instructions

Can someone tell me what this means: k2tog, yo, k2 (1,2) rep from * around. I understand everything except the (1,2)! Thanks for any help!

Hi and welcome to Knitting Help!
You’re probably making something that comes in 3 different sizes. The numbers in parentheses are directions for the medium and large sizes: s(m, l). If you’re making the smallest size, just pay attention to the first number and ignore the others. It’s a good idea to go through the whole pattern and highlight or circle all the directions for your size just to make sure you follow the correct ones.

Thank you so much! Of course, that is what it means! I should have realized that. I appreciate the quick reply. Now, I can get on with this baby sweater and maybe finish it before she arrives!
