problem in linking reports in ssrs

Question

hi in report 1 i have three filter

From date to date Number (multiple value)

when i entered from date --25 august,to date 26 august number say 1,2

its shows record

Number Feiled2 Image 10 213 image 20 214 image.

And in report 2 i have three parameter---Fro date,todate,number(same as number in report1 only one differnce is this time not multiple value) So when clicked Image it should shows the record in Report2 of all belonging of Number (10) if i clicked image in front of 10 and it did like below.

Number 2 (Belongs to number1 in report 1 ) Field2 101 A 102 B

But the problem is when i clicked image of Number 20 in report 1 ,same data in report2 shows ,but it should be like that Number 2 (Belongs to number1 in report 1 ) Field2 201 C 202 D

please suggest where i am wrong
