It's hard to say without seeing the code. Your problem was caused because it
was trying to refer to the range of the activesheet, so I forced it refer to
the range's parent sheet.

Post the whole code.

I'm back. That worked for my addsome function. But when I tried to apply
it
to my real function, it didn't work and it occurs to me that I don't
understand the soln anyway.

I thought I'd just stick Application.Caller.Parent in front of every
range()
in my function. But that gives me an error 424 Object required.

application.caller seems to return a large integer (no idea what it is)
application.caller.parent (or dot any other property gets a 424).
It seems to work in the first worksheetfunction.(,range(),) though I don't
know why, but the next occurance in the UDF causes it to drop out of
runtime.

??
Next idea?
