[ic] b_name and name

[jevon]

I am doing my card processing on my merchant's gate way on their site.  I
am colleting on the infomation on my site by the card numbe, exp date, and
card type and passing it to my merchant's site.

The problem I am having if i pass variable b_name to merchant's site and
if the client didnt enter the billing and ect. and its the same as the
shipping info how to i pass name = b_name if b_name already has no data.

Thanks ADV.
