pls can any tell me how do i correct the veritical profile for a given vertical gradient of 1 in 150 of 1200 etc and so on
If you click on the profile, right-click and choose "Edit Profile Geometry" you get this toolbar:
If you click on that button I circled in red, you get a box where you can edit the station & elevatoin of PVIs or edit the grades of tangents. 1 in 150 is 0.667% (ish).

Are you wishing to enter your grades as rise / run etc. instead of percent similar to this?
