Generally I do something like this:
$link = mysql_connect("localhost","user","password") or die(mysql_error());
mysql_select_db("db_name",$link);
$query = "SELECT * FROM table_name";
$result = mysql_query($query,$link) or die(mysql_error());
while($row = mysql_fetch_array($result)) {
echo $row['col_name1'].'<br />'.$row['col_name2'];//etc...
}
mysql_close($link);
You may also want to look at our library [webmasterworld.com] for some good threads on Basics of extracting data from MySQL using PHP [webmasterworld.com] Good luck!

Kool, but what do you do the second time/Third/etc? How do you use: mysql_data_seek($ODisplay, 0); I think this is the source of my problem Thanks

you don't need the mysql_data_seek what eelixduppy showed will loop through each result using the while($row = mysql_fetch_array($result)) { if you follow his lead and get rid of the data_seek you will figure it out

? " you don't need the mysql_data_seek"?
When I try: while($row = mysql_fetch_array($result)) { it skips the first item in the found set. When I use "mysql_data_seek" before the "while" I get all of them, Guess I've solved the problem, I'd just like to understand.

You should get all results using mysql_fetch_array unless you change the internal pointer somewhere. If you want to understand more about these two functions, read up on their documentation and look at their examples. Go to these links:
Good luck

if you have it like it is in your first post with
$row_ODisplay = mysql_fetch_assoc($ODisplay); above the loop then that is why it skipping the first row, you already grabbed it. Remove the extra mysql_fetch above the loop and it should be fine

How do I handle using the "mysql_data_seek($ODisplay, 0); " when I do two (or more) of the "while($row = mysql_fetch_array($result)) { ". I still miss the first row sometimes and sometimes I get a duplicate row. Should I do the data_seek before each "while"? Does it mater how I use the $total_Rows result? (I've been using it to skip the "while" with a simple "if($total_Rows <> 0){" Thanks tons! I really feel like I am in and endless spiral! M

yes you could do a data seek before each while, though if you need to go through the reulst more than once you could read them into an array and then walk that you can use the total_rows to skip the while if there are no results.
