If you post the UDF code we can take a look:
The most likely cause is the UDF referencing directly or indirectly cells
that are in the UDF arguemnt/parameter list.

Hi,

I have created a user defined function that is stored in my personal
macro workbook. When I change a value in one of the referenced cells,
the result does not recalc. AutoCalc is set to true in Tools --
Options, but I still need to F9 to see the resulting value. (Excel
2003.)

Any help you can lend on this is appreciated.

Henry
