Form [name] .....

will make sense (as I dont understand it; not your fault; I am just not familiar with this).

FWIW,

form *[name="customer_id"]
 form<space> means an element within <form> ... </form>
* means any element of any tag
[name="customer_id"] means an element that has the attribute 'name' with the value "customer_id"

an easy way to learn is by opening a given site and examine elements with firebug.
