HELP Trail Head Admin Trail - Beginner Salesforce1 Mobile Basics Creating object specific actions

Hello from Germany,
i think i did a wrong step while doing this challange.
I am hanging at the point where you have to create a look up relationship for activities to properties.....in first place i've done that but nothing appeard on the app. Then i deleted the look up to do the same step again. Now i get an error message:
"Validation Errors While Saving Record(s)
There were custom validation error(s) encountered while saving the affected record(s). The first validation error encountered was "Lookups on activites must have a unique domain. You can not have multiple relationships to the same object."."

Now i can't continue with this challenge.

Hello Nagendra,
Wow thanks so much, now it works.
Change to Classic Version and under Activity --> "Add a custom field to activities" --> Deleted (1). Just erase that one and try again.

Thanks
