Hello, have a problem. May be someone know the answer.

I have custom node with number field, name it "Price" or etc. No matter. Field have core settings to choose MIN and MAX value user can enter. If user enter value out of settings it get error and node not created, like field require option. How i can get MAX value from Userpoints module. I look at Rule module, ok there i can do error and etc. but in anyway node created. I don`t want to create any node. I want only check the value.

Thx for any answer. PS sorry for bad english =)
