When I update a hosted paypal button's price via the BMUpdateButton api the inventory data is destroyed. I believe this is due to BMUpdateButton killing the optional item ID data, which is not optional when it comes to tracking inventory. I'm unable to find an Item ID field in the BMUpdateButton api docs https://developer.paypal.com/docs/classic/api/button-manager/BMUpdateButton_API_Operation_NVP/ so as to preserve my hosted buttions item ID while performing a price update via this api call. So am I supposed to do the following? 1) BMGetInventory get my hosted buttons inventory and put it in a variable 2) BMUpdateButton update my hosted buttons price while destroying my buttons inventory data 3) BMSetInventory restore my hosted buttons inventory data I'd much rather just call BMUpdateButton without destroying my hosted buttons inventory data in the first place. Here's the BMUpdateButton call that I'm making via cURL: curl https://api-3t.paypal.com/nvp \ -s \ --insecure \ -d USER=itsme.com \ -d PWD=111111 \ -d SIGNATURE=john hancock \ -d VERSION=124.0 \ -d METHOD=BMUpdateButton \ -d HOSTEDBUTTONID=someid \ -d BUTTONTYPE=CART \ -d BUTTONSUBTYPE=PRODUCTS \ -d L_BUTTONVAR0=item_name=my+product1 \ -d L_BUTTONVAR1=amount=100.00
