[libreoffice-users] Sel-defined formulas insertng in Calc

Dear sirs,

I would like to insert sel-developped formulas into Calc for frequent use.
I have read the help-file of LibreOffice.org Help. 
I have made the steps suggested in that report Calc/user-defined Functions
However, the formula in the help-file does not work in Calc.
I get in Calc using the formula VOL(aA1;B1;C1) only the message #NAAM?
This will mean that the name of the function is not recognized by Calc.
What is wrong in what I have done, following the instructions in the report  Calc/user-defined 
Functions?


Yours sincerely,

Paul van Tooren
