Setting value of option button

[Glory]

Two userforms. One has an option button, the other has a command button.

Clicking the option button on the first form loads the second userform and sets the value of the option button to -1.

Clicking the command button on the second userform is suppsed to set the value of the option button on the first userform to 0.

Instead, an error message appears, which reads "Invalid use of null", and the option button on the first userform becomes gray... neither checked nor unchecked.
