Configured the sale_data as shown and modified with the amount and enabled it setting false to true, still show item not sell-able. Tryed it on multiple items and prices. The rest of the Pluggin works fine.

Any chance you can paste an example from your sale_data a second opinion is always a good way to go for this type of problem. Also have you any Rcon/console errors??

Yes, it was my mistake, i triple checked and it was a connection error with the FileZila app, i was making modification that apeared to be done on my end but never got uploaded. Tryed the procedure with another PC via WIFI worked fine =) Sorry for bothering you with this thread and i apreciate the quick response.
