For more info on how to deal with identically named controls, be familiar with the list functions, or consider choosing not to re-use names for controls.

(sorry about the previous comment, I thought the comments were still part of the account registration process; it has nothing to do with htis page and hopefully can be deleted)

What I meant to say:
"What does this really mean?
Note: If multiple controls have the same name, one form variable is passed to the action page with a comma-delimited list of values."

suppose you have inputs like this:

It means that this will be true:
FORM.textvar eq "text1,text2,text3"

It would have been much nicer if it came in as an array instead of a list; Its very easy to screw up and requires extra code to use this properly when using your own data, and practically impossible to take user-supplied text in this way. This is because the list deliimiter is a comma and therefore you must be sure that there is no commas in your data.

name=onevar value="text foo"
name=onevar value="foo, bar baz"
name=onevar value="foobar"

This will appear as 4 items in FORM.onevar, whether you want it to work that way or not. In a situation where a user isn't inputting data, it is still important to be certain that the data being used does not contain commas.

Some other languages read these values into an array on submission, so be sure if CF is not your first language that you take this for granted.

Good Day,

What does this really mean?
Note: If multiple controls have the same name, one form variable is passed to the action page with a comma-delimited list of values.

I have created a form with the following

I have created a field named RegFieldList in my database.

This is going to be my new form, but I am not sure if this is right.

checked>

Now how should my action page look?
Should I have an update query or a select query. My boss wants me to use the ListFind or ListGetAt functions. I don't know what to do can you help me.

Basically the user selects all the checkboxes that are necessary on the form page. Then I need those fields that are checked to be confirmed and appear on the new form page.

Thank you very much for helping me.
