There r 3 ways of correlating in Manual section.

We usually use the 3rd Option -Vuser Comparison

Here
1)Record 2 scripts with the same actions.
2) Compare these 2 Scripts with Compare option in the Tools. ) This will show all the Dynamic Values, make a note of this in notepad.
3)Close one of the Scripts and go to Tree View - Server Response.
4) Now Click on the Page which you need to Parametrize(Yellow icon is the symbol for Page).
5) You'll find HTTP Response under which you'll find Body - Expand Body, Expand Application Name, Expand Application Navigation Bar, Expand Form, You'll find "act" click on the "act.
6) Now you'll notice a line is highlighted. The value below is selected and Right Click and say Replace with a Parameter.
7) This will include a new Service in the Tree View and a function in the Script as web_reg_save_param.

This should work :)
