I am new to Flowcode and have been given a college project to make a simple access system utilising simple system components. I have been asked to create an admin level in which you can change user codes within the running program. I have users set up in my variables all of which have a numeric value. I am lost as to how I can change these variable numeric values to another numeric value within the running program on the keypad. I believe that it must be done through the calculation function but I cannot understand how I am supposed to do it.
Any help or useful tips would be much appreciated.
I am a newby to this so please go easy on me!!

Kind regards,
Lee.
