How do I Compare Two Objects with value number

Hello, i need help to set a value to a two different objects a then compare. For example set a "100" value number to object 1 and "50" to object 2. Then you need to choose one of the objects, if you choose object 1 you win because 100>50 but if you choose object 2 you loose 50<100. How can i do it? Thanks for all.

did you try "compare two values" ?

Yes, but i don't know how to compare the two objects instance variable with "compare two values"

[your_object_name].instance variable

Thanks, you was right. Other thing, how can i compare the objects if there are random? Example: You have 4 objects, RED with instance value 10, blue with instance value 5, green with instance value 20 and yellow with instance value 22. Two of these objects appear randomly, how can i do to compare them? Thanks for all.
