*Sigh* I may have messed this and you up.  I am regrouping and looking =
at what I am trying to do.  Jim, that was a very good idea and what it =
looks like, maybe I should be using Python to grab the data from my db?

Neither the DTML or the ZPT worked in this instance.  The form I am =
bringing in the data that has already been saved, it still does not =
bring in the check...WAIT! should I be saving the value of the checked =
box, into my table, as "checked" rather than "1"??? or does it even =
matter.

By further explanation: in the Method before this form, where I issue =
the call to the dbtable to extract an exact article, I save the value of =
the checkbox (main) to a variable called Main.  I then Set the value to =
Main in the updateArticle_html (my form to view the data).  This is the =
form that I am having the problem with.

It seems that where you issue the <input type=3D"checkbox"...> any value =
stated is what the value of the checkbox is when you write the value =
out. But when you want to read the value and the checkbox showing as =
checked is seems that the form needs to be referencing some other =
function rather then the <input type=3D"checkbox"...>  Am I off?

Don:  this question is a bit confused....

1)  Do you want to know how to create a form which has a checkbox which
is pre-checked depending on the query?

2)  Do you want to know how to process forms with checkboxes in them?

or=20

3)  both?
