help with lotables plugin

hi i bought the plugin cuz i thought the weed would show up i don't see it any where or custom tab 

The custom item tab shows up when you open the item selection menu. If you don't see the weed there, reload the plugin and it will show up

Changed Status from Pending to Not a Bug

well i finally got it into the GUIShop but when i click on it it says no item found im not sure if its the item id i only switch the skin i could not find and item id i think its for sticks just not sure why it is not letting me buy this im abele to buy the other items just not the weed once i figure this out i should be able to carry it over to every thing els
