Make second part transprency

[hendrikbez]

Good Day

I have this file M_D_1_0.xcf  that I have got the text 0 to be transparency, but can not get the right part also transparency.

I want to let it looks like this file Maand_Dag_1_2.xcf

How do I do this.

You have a layer mask. Paint / fill in black to show layers under.

Make sure the layer mask is active (click in layer icon)
Make a selection
Fill the selection with black.
Close the selection (select -> none)
