you cant assign a value like 'N/A' which is varchar, to a numeric field , so instead of updating the value field, you can display it as  'N/A'  while showing the values or else you can update as NULL

SqlServer
update   #Scorecard
set value =null  where value = ' '

You can't assign a string like 'N/A' to an int field.  As the error message states it fails when it tries to convert 'N/A' to a type of int.

That doesn't work.  try this:

select
isnull(cast(value as varchar(512)), 'N/A')
from #Scorecard
