I am trying to use a custom function, in a file that is shared with other users.

It doesn't matter how simple the function is, I don't have the value assigned in the "return".

Only get  "#EVAL!" response. 

This is one of my functions, the simplest (made for debug):

If I give the execute option to test the function, I have that everything is in order and the response value is correct.

In other of my  own documents, i have not problem with this. 

Please ! can you help me!
