AS,
Do you mean the input called 'list'?
<INPUT TYPE="hidden" NAME="list" VALUE='ABC
It's not visible because the type is 'hidden' instead of 'text'.
I don't know whether this is a concern but your HTML is extremely non-standard. You end the head twice (</HEAD>), your form tag doesn't have an action or method (forms are used for user input, there's no need to have it just for the information content). Important here is your input and its value attribute are never closed! You need to add a quote after VALUE='ABC to close the attribute, then /> after that to close the input field.
Also, there are plenty of non-existent (or mis-used) tags in your information section: it appears as though you're using XML-type syntax for storing a database within an HTML page....
Anyway, try making the input field text not hidden, and close it properly and see how that works
