Fluid Voronoi Shape

Hi,

I am currently trying to create a fluid voronoi shape by mixing the vornoi definition with the weaverbird defintion but for some reason when I connect the two defintions the volume in the weaverbird defintion does not work, therefore the fluid shape is not produced. Is any body able to help?
