Question about Custom

Hi guys,



I have a question about custom on SA-MP.

I have three files : newtent.col, tent.dff and tent.txd



It's possible to add this new object ? And how ? Because I added this three files in Custom.img and I have add this line : 19000, tent, tent, 299, 0 in custom.ide but in the game, I mean nothing.



Thanks for help :).
