How to perform a count on cancelled meetings in Outlook report

[Anonymous]

I want to use a card visual to count the number of cancelled meetings within the 'Meeting Request' fields. 

I know there is an 'IsCancelled' field however this is null for everything within the report from Outlook. 

Please can someone visually show me what to do ?

@Anonymous , You can count if it has some non null values

countrows(filter(Table,not(isblank(Table[IsCancelled]))))

@amitchandak The whole column is null. Is there a way to query whether the subject line starts with 'Canceled' which would count the number of cancelled meetings?

@Anonymous , you can  try search, find, containsstring or left 

a new column example 

if(left([Subject],8) ="Canceled",1,0)
