This would be kind of difficult to explain to a new person and not really understand how this tutorial you are following actually works but I will give it a shot.

Your query is returning null because it isn't finding anything in the database with that creatures name. The creatures name is coming from the $_GET super global variable which comes from the url Which seems to be battle.php?creature=somecreaturenamehere. When you first click the link to go there is there a creatures name in the url at the end? If so, do you have that creature in your database?

Also, can you please use the code button and put your code inside there next time please? It just makes it easier for people to read it and see what's going on Or use [*code*]code goes here[*\code*] without the stars

In battle.php monster name see.
In battle.php?creature dont see.
Screens:

I recommend watching all the way to video 14 then doing after that. The videos are very old and some things are depricated.

It looks as though in the player table the creature on the player is wrong or missing. Check that field to see what is happening.

Table it's okay.
In attack.php errors, why?

I fix it.
There it was misspelled.
$createinfo2 -> $creatureinfo2
