Here is the code:

 

 

 

<?php
session_start();

include "database.php";

#Line 10        
        #Ge $dbQueryHealth ett värde 
        $atkuser= mysql_real_escape_string($_POST['atkuser']);
$querythe =("SELECT temphealth FROM characters WHERE user='$atkuser'")or die(mysql_error());    
        #Sätt $currentHealth med värdet från databas-resursen $dbQuery 
        if(mysql_num_rows(mysql_query($querythe)) == 1)
    {
        $currentHealthEnemy = mysql_fetch_assoc(mysql_query($querythe));
        }else{ die("User Don't Excist. Please Go Back And Try Again");}

            } else {

See if removing the space after the 3 mt_rand helps.

When posting, please point out what line your error is on so we don't have to guess or count.

 

I assume line 49 is this:

            if(($currentHealthEnemy - $healthAward) > $minHealth) { 

 

 

Earlier in your code, you assign an array to $currentHealthEnemy:

        $currentHealthEnemy = mysql_fetch_assoc(mysql_query($querythe));

 

 

So, you're trying to subtract a numeric value from the whole of an array....not allowed/possible.
