Craigh,

A Clipping Path has to be closed and form the shape af the intended mask.

You can use the black squiggle as it is for an Opacity Mask as follows:

Select both the squiggle (on top) and the green burst and click Make (Opacity) Mask with both Clip and Invert Mask ticked.

Opacity Masks are all about appearance, more straightforward to use in many cases.
