Doing Math - What is Wrong?

I’m trying to add two variables together.
I figured Wappler was getting confused when adding values straight out of the database, so I’ve made variables that have the same value.

But, Wappler does not want to add them together for some reason.

Is this correct?

The code:

So you can see the output…
Each variable on its own is outputting the correct value.
When added together it doesn’t work.
