HTML variable question

[Paul Ramsey]

Brent,
Yes, it's great!
If memory serves, it's as easy as putting this in the rest of your  
template form:

<INPUT TYPE="HIDDEN" NAME="trip" VALUE="[trip]">

Only issue is you might want an initialization value at startup,  
which you could pass in as a GET parameter in the page opening link.
