I think that will be last record. Have one more extra section in Section Expert of detail section write suppress formula
not  onLastRecord to display only for last record. Also select suppressIfblank on in section expert.

Create one more formula with following code

stringVar str:=" ";
numbervar i;
for i:= 0 to 17-RecordNumber do
    str:=str+chr(13);

str;

and place the same in the detail section.

Hi, Thanks Venkatesh,
I was searching for a way to do this too, you're a lifesaver!
