"other period" data selection not working

Hi,

In a customized z report, on the initial selection screen there are options- today,current month, current year, up to today, other period. The option "other period" is not working. When I enter the data period, instead of showing the data of that selected period, the report is displaying all the records for all periods.

My question is how to correct this "other period" option and how to make a selection test variant.

Please reply.
