DEBUGGING

When I click the green flag, the name variable has a name in it. It should be blank or 0. How can I fix this?

When I enter a name into the program, it doesn’t display the name in the sentence. How can I fix this?

Madlibs Build Guide

Unit 3.3

Select or design a backdrop and select 1 sprite from the Scratch library to add to your project.

Click on the Variables category and create the variables using the names you created in your planning guide.

Create a green flag clicked script that sets the starting variable values.
Create another green flag clicked script, that starts with a “wait 1 second” block that asks the user to enter the variable values. At the end of this script, include a broadcast block to send a message to the ‘when I receive’ event block in step 5.

Create another script starting with a ‘when I receive’ event that uses a say block. Put join blocks in the say block. Put text and variable blocks in the join blocks to display your Madlib.

**You can include “wait” blocks in between your “ask” and “set” blocks to allow enough time to read the questions!
