Packing slip problem

[Sharx]

I've added the price of each product and the total price to the packing slip.
But the table heading is showing the code:

TABLE_HEADING_PRICE_INCLUDING_TAX
TABLE_HEADING_TOTAL_INCLUDING_TAX

Instead of the heading text.
What am I doing wrong?

Isn't the end result the same as printing an invoice without the word "Invoice" at the top?

Yes it is ;)
I just didn't want to display the the price without tax because it show the same as with tax.
I didn't get the tax to work in Zencart for some reason.
Anyway, I fixed the paking slip... I just replaced the code with text instead.
