sock whoas

So I am going to throw this out to you all and maybe there will be hope for me yet. I recently finished the sock called flat feet and have moved on to the second one. For the life of me I cant get it to start right. I have tried everything. I get the cast on going just fine and start the round. And when I think it is going good it is to loose and looks like a long piece of yarn that isnt to be there. This is probably not making any sense, but it is almost as if I am not making it tight up to the needles. If you have experinced that before. Maybe some one knows what I am rambling on about. If so Please give me suggestions to try to get this sock going.
