Here is screenshot of my app.
Every time the user clicks on button "50 naira", this adds 50 to every entry and the same goes for 100 and 200 i.e 100 and 200 respectively.

I will like the total to display the sum of all entries i.e 50,100 and 200. For example the user presses 50 naira button once and 100 naira button once, I will like the "Total" text box to display 150 naira which is the sum of the two entries.

I cannot see your picture, therefore I can only guess what your plan is.
This may be just what you want:

But it seems that it will be very helpful to you to learn more about App Inventor first.
