PayPal solution
Hi. The PayPal solution was as follows:
The variables are shipping_1 and shipping2_1.
This would charge (<%=WA_eCart_GetShipping(spCART)%>) shipping for the order regardless of how many items are purchased.
<input type="hidden" name="shipping_1" value="<%=WA_eCart_GetShipping(spCART)%>">
<input type="hidden" name="shipping2_1" value="0">
Seems to be working.
