Hi.
7 days I use this component for make beutifull xml feed. But, i have big problem. I can not make "mapping" for product availability. is here any person, who work with this component?

1. i make mapping category as "availability"
2. in this category i make first test items "3-5d" . . . . Local value = 3-5d.png; External value = 4;
3. i make element "DELIVERY_DATE" . . . . Element type = virtuemart/product_availability; Select Maping.

Generate xml and have <DELIVERY_DATE>3-5d.png</DELIVERY_DATE>

But need: <DELIVERY_DATE>4</DELIVERY_DATE>
