how to get the data with date difference.

hi,
i have an issue as i want to search the data by putting the date difference. i am attaching the file. lets say for example: i want the interactions between the date 20th feb,2013 till 20 th may 2013 ,then i shall be able to get the complete rows seen in sheet named "search".

in this file u will see the data in each sheet for each client of mine.see the rows 28 and column 3 that have dates on with particular interactions takes place and i want that it should copy all the rows that have the date that got included in the date difference input by me .
