Calculating the Total

Every time you save a new time, you are going to add it to the value of totalTime.

Hover over the totalTime variable and grab a set global totalTime to block. Attach it below the add items to list block.
From Math, take the + block and attach it to set global totalTime to.

On the left side of the +, plug in a get global totalTime block. On the right side, plug in get mins.

You can find the get and set blocks for a variable by hovering the mouse over the name of the variable in the orange initialise block.

You can also use the get and set blocks located in Variables, and then click the little arrow in each block to choose your variable.

Now, display the total so the user can see it!

Go back to the Designer view and add two more labels to your app. Set the Text property of the first one to Total minutes exercised:
Change the Text property of the second label so that it’s blank, and make a note of this label’s name (for example, Label2) so that you can set it to the total in your code!
If you want to, change the size and colour of the labels. I’ve made mine blue and checked FontBold to make them bold, and I changed the FontSize of the second label to 50!
Switch back to Blocks and add a set Label.Text to block to your code, together with a get global totalTime block (choose the label name you made a note of above!).

Here’s what your code should look like:
