How to display the PI index on the alignment plan

[Engineer_learning]

Hello,

 

I am very new to civil 3D and while I seem to be starting to get the hang of things I am having trouble getting the plan view of my alignment labels to show the display the info I want.

 

I would like for the late at each PI to say:

 

PI : (and now have the program count the relevant PI index numbers and add them)

 

I have not been able to get this done. If I steal the text from the profile band style where it has alignment index and paste it in the alignment style it just appears blank.

 

any help would be great!
