Thank you very much!! it made my day

here is the code. <?php $request = mysql_query("SELECT * FROM database WHERE ean = '12' ") or die (mysql_error()); $calculation1 = ($price / $weight); while ($row = mysql_fetch_array($request)) { echo "$row[name] and $row[weight]<br>"; echo "$row[price] and $calculation1 <br>"; echo "<br><br>"; } Can you explain more? I have the calculation after selecting data from the database. Should i put the if statment before the while, is that what you suggest?

Dear people, I have a problem for solving. I have numbers in my database saved with decimal atribute. The numbers go below zero like this '0.55' and also above zero. I' m just testing my code and i came to this Dividing by zero problem. I need to do simple devision $variable / $ variable to get a needed number for my operation, but it just does not work ... help me pls. If i do it manually it works for ex. 0.55/ 0.2 = 2.75. I need to get this same output from my variables. I do much appriciate any hints where to fix this
