How to show a transient variable in an animation

[royyang]

I have a question about writing a changing variable in the animation. I have a data file now looks like below:

VARIABLES = X(m),Z(m),Index
Zone T="Air_Particles",DATAPACKING = POINT,SolutionTime = 0.25000000000000000 StrandID = 1
0.25000000D-01 0.00000000D+00 1
0.12500000D+00 0.00000000D+00 2
0.22500000D+00 0.00000000D+00 3
:

:
With data of different solution time, Tecplot is able to animate the motions of the air particles. And by inserting a text box with "Time at &(solutiontime)", the animation looks like:
Time at xxx
(Movement of air particles)

"xxx" stands for the time instant which is changing. Now I would like to see the value of a variable which is changing with different time instant, for example, the total number of air particle, N_Total. And the final effect looks like:
Time at xxx
Total number of particles is N_Total
(Movement of air particles)

Here N_Total is changing with time which I can write somewhere in the data file. Could someone help me how to write the date file or where to find in the Tecplot user guide?

Thank you very much in advance.
