plz,help me about the code's problem

i was trying to text a pickup.dis. and i hope for it can analyze how many Health Potion in the package ,if the number is bigger than 50 then do not pick up anymore .



here is my code:

*****************************************

[NAME] == "Health Potion" >=0 [PICKUP]

[NAME] == "Health Potion" == 50 [IGNORE]

*****************************************



i've used it and its not working. I thought that missing something like"how to let the bot dim the Health Potion's number" or "how many health potion in the package and check it before pick up"

i just cant figured it out how to dim it or check it. i thought the problem might be i have not give this text a logic about it.

But i don't know how to set this in program logic ....



and im using the customize text,so my demonbudy can't control that how many health potion should pick up.

plz help me............
