This MBlock code has error when try to upload



Can anybody troubleshoot this.




It is because you typed A into the block instead of dragging and dropping the variable named A into the truth block.

Go to variables and pickup the orange round shaped block call A and drop it in.


Use the variable in the condition, not a typed letter
