TSM. Don't post items that don't have a "sale rate"

Hey!
I have a little problem with TSM auctioning operation. I wanna skip all items that have a saleRate below 0,01

My string is working. But whenever TSM read this:

 ifgte( DBRegionSaleRate, 0.01, max ( 110% crafting ) ) 

I see an error in my chat:
Did not post "ITEM" because your minimum price is invalid. Check your settings.

Maybe because TSM doesn’t see this value for an item that doesn’t have “sale rate” in the tooltip. Or maybe because TSM is looking for a price, but an if-function returns only “false” value and TSM doesn’t know what to do

I apologize for my English. This is not my native language, but I hope you understand me <3
