VHDL question (solved)

[Dago]

I have an entity with a generic of type natural. Then I have a function which takes a natural number as an argument and returns a natural number. I then try to create a variable in the entity with such as "variable foo : unsigned(my_function(my_generic) downto 0);" and modelsim will complain "no feasible subprogram found" about the my_function call. I pretty much also tried different types for the generic and function return type/argument etc. but no dice. This function works fine when called with for example some_other_variable'length but not with the generic.

What is happening?

Edit: Gah solved, I had an enumerated type the same name and I didn't realize this due to case insensitiveness...
