My noobish exercise plan. Please help fix.

[Jack Bando]

I don't know much in terms of exercise, as what works and what doesn't. Here's my plan of what to do, please show me what's wrong with it/what's missing.

Daily/every other day plan (Which one-every day or every other?)

Pushups
Dumbell Curls
Dumbell Hammer Curls
Dumbell lifts (arm straight down->arm straight forward)
Crunches
Squats

What's wrong with this? I don't know much about this stuff and would like help. Thanks
