Issue in Report with two dataset

system_migrated

Can You tell me please how to compare field of one dataset with the field of other dataset in scripted report.

Actually my problem is that i have to change the color of row value of dataset2 by comparing its value with whole values in other row in dataset1 , i have tried this by inserting table with dataset2 in the detail row of table binded with Dataset1, but the it is comparing value with current value of dataset1 row and data is also coming reaptedly.

so my problem is that i have to compare current column value of one table with all values of same column in other table if they matched then value should be displayed in blue.

please help, i will be very thankfull
