My data from my loop is being mismatched, not sure why

I have a code that is suppose to display messages back and forth between the users. For some reason the data is mismatching and I'm not sure where in my code I have the error. I've tried to change my if statements of $x < $sender but that didn't work.

but the data being displayed doesn't line up with the database information.

"Test 2" message was sent from woof3, so it should be green and not blue when logged in as woof. And "test again" was sent from woof, so it should be blue when logged in as woof

Please help!

// Typing part of message
echo '</div>

I can add more info if needed.
