So i've made a virtual thermostat that i want to affect change on a servo motor that will control a vent position via a ESP8266 using espeasy

In the blockly i have so when i go in and change the setpoint on the virtual thermostat i go back and look at the blockly and instead of looking like above it now looks like this how can i keep it a variable tied to the setpoint rather than being permanently set to whatever the setpoint was just once

scratch that, i had things in Fahrenheit and somehow things weren't quite matching up. when everything is Celsius it was happy.
