Use the Summation operator with r in the bottom placeholder.

Some additional remarks:

1.  P.3(r) is not a vector even though it looks like being one. Its a misuse of a range variable. Try to assign it a variable like  p:=P.3(r) and you will get an error.
2. Are you aware the the last value in your range r will be 629,5 mm and NOT 630 mm ?
3. Can it be that you are rather looking for the integral and not the sum?
   
   P.S.: Of course you will get a different result with your function P.3. I had to create a dummy function because unfortunately you did not attach your worksheet.
