For some reason, changing the variable does not work.  
At the same time, the value to which it needs to be changed is calculated and output separately fine. But when changing on this value, the code reacts as if it is empty.

Hi and welcome to Thunkable!

The problem is that you are using a variable where the name of a variable should be. The `change app variable " "` block is expecting a text string such as “cromen” but you are giving it _the value_ of `app variable cromen` instead.

The solution is to not use the set or change app variable blocks at the bottom of the Variables drawer and instead only use the ones at the **top** that have a drop-down menu for choosing an existing variable.
