Try this:

php Code:
Original - php Code 
  1.  
  2. <?php
  3. mysql_connect(localhost, username, password);
  4. mysql_select_db(database);
  5. $result = mysql_query("SELECT * FROM table");
  6. $i = 1;
  7. while($row = mysql_fetch_array($result))
  8. {
  9.     if(($quot = $i % 2) == 0)
  10.     {
  11.         echo '<font face="Lucida Sans Unicode" size="2" color="#000066">';
  12.     }
  13.     else
  14.     {
  15.         echo '<font face="Lucida Sans Unicode" size="2" color="#CCCCCC">';
  16.     }
  17. $i++;
  18. }

Ooops, I will try to explain. You did this:
php Code:
Original - php Code 
  1. if($row2['COUNT(*)'] / 2)
Which will always return true ( greater than 0 ) ... for a better explanation start here http://www.php.net/manual/en/language.types.boolean.php

The code that I sent you will use the color 000066 on false and CCCCCC on true. For more information on the % operator see http://www.php.net/manual/en/langua....arithmetic.php

Hope that helps.

RE: Alternating Text Colours
For clarification, true is any non-zero value ( greater than or less than ). Not just greater than as I previously wrote.

My apologies.

RE: Alternating Text Colours
Thanks for the help evilive..although, the code you gave me, didnt quite work...just for the record, i hate to change this:
php Code:
Original - php Code 
  1.  
  2.     }
  3. $i++;
  4. }
  5. echo "{$row['something']}</font><br>";

to this
php Code:
Original - php Code 
  1.  
  2. $i++;
  3. echo "{$row['something']}</font><br>";
  4. }


just had to put the echo something inside the while loop
