Have you ever written a DAX formula and gotten an error message you didn't understand? 

 

Please take a 3-minute survey here: http://aka.ms/DAXErrors

 
  For instance:

  • "The end of the input has been reached" or
  • "A function 'Calculate' has been used in a true/false expression that is used as a table expression. This is not allowed."

Are there any error messages that you've seen that you would like to be clearer?

Thanks for your feedback!
