[ic] [add-item] problem

[Grant]

I'm having some trouble with the add-item usertag.  I'm using it to
add an item to the shopping cart based on user input before anything
else is in the cart.  If the same item is then added to the cart
through normal IC means, it is added as a new line instead of
incrementing the original line item.  I do have "SeparateItems No" in
my catalog.cfg and it works great otherwise.  Here's a link to the
posted tag:

Adding more of the item via a normal form increments the second line,
and adding more of the item via [add-item] increments the first line.

The whole thing does work properly if an item is added to the cart via
normal IC means first and then added via [add-item].  Any ideas?
