Have problem wit [] in script

How to "hide" [] in script

[Marshall]

I have a script I'm using to validate checkboxes. It forces the user to select a specific number of boxes. Each of the boxes is name="Dazs" There is a line in the script the reads:

for (i = 0; i < document.RegistrationForm.Dazs.length; i++)

The problem arises in that the form is processed using php which requires empty [] in the input name with multiple choices:

name="Dazs[]"

If I enter the [] in the script:

for (i = 0; i < document.RegistrationForm.Dazs[].length; i++)

the script returns an error. Question, how do I keep the brackets in both the "name" for the php and in the script so it knows what inputs I'm referring to?

Any help would be appreciated.

document.RegistrationForm["Dazs[]"].length

should work iirc.
