I cannot wrap my head around why this code:
"""Provides a scripting component.
Inputs:
Run: Toggle component On/Off
Label: Set Label of the component for easier identification
Update: Manual update
Pause: Toggle automatic update On/Off
Low: The Lower value
High: The Higher value
Normalized: normalizing the "distance" between Low and High
Output:
out: supposed to be console output, but I don't know how to get it
Value: The a output value

results in this:
Why the values of the two sticky variables are both 100?
Could anyone point out where my mistake is?
Thanks in advance.
