No path from latent variable to observed variable

Hi!
Im suppose to do a mediation analysis of one independent variable who affects the dependend variable in the SEM builder. When I set the medasurement component for X and Y and draw a path from X to Y and click estimate I Stata is only working. I get a error message: model not identified;
no paths from latent variable LOYALT to observed variables
How do I solve this problem?

Thank you in advance
