PHP may not be this way, but I think that it is. If I am incorrect, please let me know. I hope this helps out (with something).

Kim,
Won't redefining the variable destroy the MySQL Resource, resulting in a resource invalid error, like he has?
$pic = mysql_query($sql,$connection); //Defines variable
$pic //Redefining variable, dumps old contents = //calling on an invalid MySQL Resource, because it doesn't exist mysql_fetch_array($pic);
My comments are in green.

Well, your query looked confusing to me, but break it up like this
First :
select
Then, name your coloumns, seperate with commas, or use wildcard for all

Define from what table you need to select
FROM database_table
Add some select statements with WHERE
WHERE
and the statements itself
1=1
What did I just write now? Looking at your example I guess : 1. you need the coloumns : Rune, username 2. your table : RuneRunner 3. your select criteria : UserID=3
I would then write your SQL query as this :
$sql = "SELECT Rune, username FROM RuneRunner WHERE UserID=3";
Then you could do your code, $pic = mysql_query($sql,$connection); $pic = mysql_fetch_array($pic);
You would also want to add a database abstraction layer, as for debugging
purposes this will make your life much easier.
Your original code looks to correct if you rewrite it abit, like this :
SELECT RuneRunner_1.Rune, RuneRunner_1.username FROM RuneRunner RuneRunner_1
WHERE (RuneRunner_1.User_ID=3);
Not tested but it should work fine. On the other hand, the referencename
after the
table name should be a short one to make the statement much easier to read,
somthing like :
SELECT rr.Rune, rr.username FROM RuneRunner rr WHERE (rr.User_ID=3);
Then again, since you only have one table in your statement there is no need
for the reference name,
and since your WHERE clause is a single statement there is no need for the
paranthese either.
So you are still back to :
SELECT Rune, username FROM RuneRunner WHERE User_ID=3;

why doesn't this work: $pic=mysql_query('SELECT Rune, username FROM RuneRunner RuneRunner_1 WHERE (User_ID = 3)',$connection); $pic=mysql_fetch_array($pic);
