How to give compatibility to an item in the item forge?

[johan 2]

Hello friends, I'm trying new things on my server and I'm trying to create a new item class, a new Item_type. But I have difficulties so that this can be forged. Now look for the line of the variable and add the Item_CanJinglian_ID in the Item_CanJinglian_Num, but still I can not get my item to be forged. I have only achieved this by changing the Item_Type of the item in the iteminfo.

this is my error when trying to install it
