[ic] Shipping Calculation problem

[Doug Finley]

Hello All,

I am having a tough time adding an additional calculation to a shipping
lookup.

Running 4.8.1
RH 7.1
PERL 5.6.0

My shipping.asc file looks like this:

uspspm Priority Mail weight 0 0 e Nothing to Ship!
uspspm Priority Mail weight 0 70 u PM [default zip 194] {'ui_ship_type' =>
"weight", 'zone' => "194", 'table' => "PM",'ups' => "1", 'adder' =>
"([subtotal] * .01 ) * 1.00", 'at_least' => "3.95", 'geo' => "zip",}
uspspm Priority Mail weight 70 999999 e Over 70 lbs. Postage Pending.

The lookup works great, but interchange is ignoring the adder.  I based it
on the samples in the interchange docs, and it does not seem that different
from what others have posted to this list either, but alas, when I reach the
checkout all I get is the shipping charge.  I know that I have done
something wrong I just can't find it.

Any help is appreciated.

Thanks,
Doug Finley
