Calculate duration

Questions & Help
1

I’m trying to calculate the duration of the time my pool pump needs to run, based on the water temperature.
The flow itself works, when trying an easier formula {{(temperatuur/2)*3600}} for example, then it works.
But the formula i’m trying to set is {{((Temperatuur/2)-(0,2 *Temperatuur))*3600}}
However, i’m not getting any value stored in my variable.
It’s probably a syntax error, but i can’t figure out which one.

Suppose it is . Instead off ,

So {{((Temperatuur/2)-(0.2 *Temperatuur))*3600}} will do the trick

Thanks that worked!

Could you share your flow?
