Have a look at:
http://groups.google.com/group/comp.lang.idl-pvwave/browse_t hread/thread/1ca56b9c2bcad51/58a5fe20a6d16341?lnk=gst&q= Attempt+to+store+into+an+expression+triangulate#58a5fe20a6d1 6341
It boils down to having to define the x, y and fvalue variables before
passing them to triangulate so they can be sorted properly.
Take care,
Chris
