Dropdown's to lookup data

Hi all!

I'm sorry for my bad English but I really need your help to solve my challege.
I have a workbook, there are three sheets which named "Actual" and "Plan" and "Report" in this workbook. Now, I have to put the data from sheet "Actual" and "Plan" into sheet "Report". I don't know how to explain clealy to help you understand but I mean: First, in sheet "Report", if I choose a value from drop-list at cell C5 (for example I choose Group1) then I choose a value from drop-list at cell E5 (for example I choose T1) then the data of both sheet "Actual" and "Plan" of Group1 at column named T1 will be put in sheet "Report".
Sorry for this point I can't explain clearly, but you can see the worksheet I've attached to understand what I mean, so you can help me.
Thanks,
