Global number and global color

When using a global number in a child component, the value is 0 (I used $bi(level)$).

It is correct when editing the formula, but is 0 when you are in globals list.

Also when creating a global number and don't set a value, the value is nothing. When used in a formula, it dhows the calculation with an empty string where the unset value must be.

When I set a color function to a global color, the child component can't inherit the parents color. This is a long time issue. Probably related to these issues:

I usually use Text as global variable to store number or color, so that it can be override from within any child element (through Touch action) or If condition.

Hope this helps.
