Command won't work when there is no item

Hi. I have flash mod. I made a flash ring there. Right click on the ring gives me flash items and ring in working condition. But when I right click on the ring without the armors, it reverts as if there were armors. I am here if there is no armor; I want him to write a letter that please put that armor in your inventory and that the ring is not changed. Is there a method for this?
