Distance calculation with RELATED

I've not been able to get my distance calculation working.  I'm following a solution on another post, but the only difference between this one and mine is that some of my coords are in another table so i am using RELATED.  My code is:

 

 

Distance = ACOS(SIN('LB_Incident_Post1970'[Incident_Latitude])*
           SIN(RELATED('GIS.LifeboatStations'[Stn_Latitude])+
           COS('LB_Incident_Post1970'[Incident_Latitude])*
           COS(RELATED('GIS.LifeboatStations'[Stn_Latitude])*
           COS(RELATED('GIS.LifeboatStations'[Stn_Longitude] - LB_Incident_Post1970[Incident_Longitude]))
*6371)))

 

 

Can someone spot where i have gone wrong? I'm getting the error "Function RELATED expects a fully qualified column reference as it's argument".

@rogerdea , seem like a problem with ) , check one in bold

 

Distance = ACOS(SIN('LB_Incident_Post1970'[Incident_Latitude])*
SIN(RELATED('GIS.LifeboatStations'[Stn_Latitude])+
COS('LB_Incident_Post1970'[Incident_Latitude])*
COS(RELATED('GIS.LifeboatStations'[Stn_Latitude])*
COS(RELATED('GIS.LifeboatStations'[Stn_Longitude]) - LB_Incident_Post1970[Incident_Longitude]))
*6371))
