I would like some help with JS, as I am not familiar.
I have (field_112), which is Employee
I have (field_9), which is Project Name
I have (field_77), which is Start Date
I have (field_118), which is End Date
The Employee field allows for more than one Employee.
I would like a pop-up window, alert, or similar action to take place when a user tries to schedule an employee on a day when the employee is already scheduled between the start and end dates on a different project.
I hope this makes sense. Thank you!
