works fine, thanks.

works fine now, too.


Another question:

How to use FormulaManager.remove() ?

I added 

  fman.remove("f") 

to the end of the example, but I get 

visad.formula.FormulaException: Cannot remove variable f because other 
variables depend on it!
        at visad.formula.FormulaManager.remove(FormulaManager.java:276)
        at FormulaManagerTest.main(FormulaManagerTest.java:61)

Which variables depend on f? (BTW, the same happens for remove("x")).

Timo
