my online chat is glitching can you help me? sorry don't know how to describe it. https://scratch.mit.edu/projects/527745222/

1. Cloud variables can't contain letters (did you read the notice that appears when you make one?)
2. This is a problem with the

<(Space to chat) = (true)>

block. It doesn't report whether or not the variable/list is showing. You need another variable to do that.
3. You messed up the connection script.
4. I didn't know how the chat function worked without looking in the code.
5. CLEAN UP YOUR CODE
6. Grammar: “You are the blue scratch cat” not “you is blue scratch”

ok

instead of setting the cloud variable to a word, make it set it to a number which says the message from a specific list item in a list

You were trying to put letters in cloud variables.
