Baffled by Pattern!

Here is what my pattern says ( and I confess I’m a relative newbie) -
"Knit 2 (2,2,2,2) [1,1,1,1] rounds straight"

Hi and welcome to KnittingHelp and to knitting!
It looks like your pattern comes in a variety of sizes. At the beginning the pattern will give you the different sizes in the same format, one size outside the parentheses, the parentheses and then the brackets.

Can you give us a link to the pattern or a pattern name?
