"Formatter Doesn't Exist for Type Number" Error With .setValue in a Flow

Wappler General Need Help
1

My next app feature will require me to do various bits of maths in a page flow and pass the values back out to some dmx variables. I’m having problems passing the values back out and encountering the “Formatter Doesn’t Exist for Type Number” error message.

@teodor, could you show me how to do this without getting the error please? (I’m using Wappler 6.0.3)

Let’s take a simple example of X+Y=Z…

Just use a name different than z for the Assign step. It should not be called same as your variable z.
