Hi Naomi,

The confusing part is that your code

STORE this.BackColor to ("res4." + shapeX + ".backColor")

Does exactly the same as his code

STORE "res4."+ shapex + ".backcolor" TO back_color
&back_color = this.BackColor

In both cases, RES4 has to be an object reference and shapeX a string containing the name of the shape object.
