Adding the following after '//total counts' provides nicer formatting for 'long' and 'longweeks' where days, weeks, months or years is 0.

// set text variables - Added by Juergen May 2016-04-19
yText = If ( y = 0 ; "" ; Case ( y = 1 ; y & " year" ; y & " year" ) ) ;
mText = If ( m = 0 ; "" ; Case ( m = 1 ; m & " month" ; m & " months" ) ) ;
dText = If ( d = 0 ; "" ; Case ( d = 1 ; d & " day" ; d & " days" ) ) ;
wText = If ( w = 0 ; "" ; Case ( w = 1 ; w & " week" ; dw & " weeks" ) ) ;
dwText = If ( dw = 0 ; "" ; Case ( dw = 1 ; dw & " day" ; dw & " days" ) ) ;
longText = Substitute ( List ( yText ; mText ; dText ) ; ¶ ; ", " ) ;
longweeksText = Substitute ( List ( yText ; mText ; wText ; dwText ) ; ¶ ; ", " )

This line:

yText = If ( y = 0 ; "" ; Case ( y = 1 ; y & " year" ; y & " year" ) ) ;

Should read:

yText = If ( y = 0 ; "" ; Case ( y = 1 ; y & " year" ; y & " years" ) ) ;

(I missed the 's' off of 'years')

I have updated the function to include the enhancements suggested by Juergen - sorry it's taken so long to notice them!
