How can I transfer one control value to other control

[REDUANUL]

This is the way that I solved my problem (as per my project feasibility):

The reason why I needed that is, Input B will be updated after placing some values to Input A so that users do not have put the same value again. The next step will start either the value of Input B or another value but not beyond the Input A value. Another thing was Input A should run independently. The above logic meets all around. 

Problem and solution was simple but you know sometimes simple things pinch too densely 😕

Well, that's not really a solution to the original problem because:

• B can only be made larger than A, never smaller.
• If B is already larger than A, making A smaller does not change B.
• Whenever the TRUE case executes, "Input 1" will turn to zero for a nanosecond (or longer if there is a reasonable loop delay)

These all seem unwanted side effect and don't agree with the original specifications.

Here's my version again, just now with the two outputs correctly connected.

(As said, you also be able to do something with event structures. really depends on the rest of the code)
