Hi Experts

the DAX code below, tried multiple ways to filter the applicant id , so that if its found in project number to remove it from the count, wondering if you have another way to count applicant ids where status is accepted and they are not found in the projects table

VAR Applications      = CALCULATE ( COUNTROWS ( 'ApplicantDetails' ),'ApplicantDetails'[ApplicationID] <> ProjectNumbers, ApplicantDetails[ApplicationStatus] = "Accepted")

FlightRisk = 
VAR ProjectNumbers    = VALUES(CoreGrants[ProjectNumber])
VAR ApplicationNumber = VALUES(ApplicantDetails[ApplicationID])
VAR Applications      = CALCULATE ( COUNTROWS ( 'ApplicantDetails' ),'ApplicantDetails'[ApplicationID] <> ProjectNumbers, ApplicantDetails[ApplicationStatus] = "Accepted")
VAR Projects          = CALCULATE( DISTINCTCOUNT ( 'CoreGrants'[ProjectNumber] ),'CoreGrants'[ProjectStatus] = "Live")
VAR Total             = (Applications+Projects)
VAR Output            = Projects&" Live 
"&Applications&" in progress apps 
"&Total&" total"
Return
(Output)
