Welcome to Knitting Help!
There is a video here in KH for picking up stitches.

See if that helps. 
thank you for your reply but it did not help much when my pattern says pick up and knit do i pick them up and then knit a row
Not really, picking them up is the same as pick up and knit in one action. It used to be that people would pick up stitches with the left needle, then knit them, but now most people do it all in one.
