In this video, you'll add variables to store the votes for each item on your fashion poll.

Computer scientists use variables frequently in programs to store values that will be displayed or used later.

You'll need a variable to indicate how many people voted for items on your poll.

To add a variable select a sprite to track.

This example uses the yellow sneakers.

Next click on the data menu and click the make a variable button.

Name the variable something that makes sense for the sprite you selected.

In this example it's called sneakers.

The name will be displayed below the sprite.

This variable will store the vote count for the yellow sneakers.

Click okay.

Then place the variable read out under the sprite.

Drag the change variable by one block into the scripts editor.

Click the change by one block.

The variable value will increase by one each time you click the block.

However nothing happens when you click the sprite.

You still need to click the code block itself.

Click on the events menu and add a when the sprite is clicked event.

Now each time you click the sprite the value of the variable should increase by one.

Great work.

Now you'll be able to keep track of every vote cast for this sprite.

Next create the same code for the other sprites in your poll by adding a new variable and tracking the clicks for each sprite.

Now it's your turn.

For each sprite make a variable and add the code to change the variables value by one each time the sprite is clicked.

Remember to test your code frequently as you work.

That's how computer scientists find problems early before they have created too much more code.


  1. Make a variable.
  2. Name the variable.
  3. Change the variable value by 1 when the sprite is clicked.
  4. Repeat this process for each sprite.
