Hide Duplicate rows

I am creating a report based on a group value and hiding the duplicate values by clicking the hide property on the selected textbox. The report values are displayed in two rows. If in the same group there is a same record then I am not displaying it.

Which works fine,but it is leaving a blank row all over the report. Please guide me as to how do I avoid the blank row if I am hiding duplicate values on a row.

example:

1 joeph test 111 222 red

sample done works

2

joseph test works

If in the same group, if the 1st line repeats for the 2nd row then there is a blank row after hiding duplicates. I want to remove that blank row if row repeats for each group
