I am using Dreamweaver CS6 and the syntax check in my software say: "No syntax error" What am I doing wrong this time? Thanks for your good advice! Karl

    You do a var_dump on each variable to see what type they were

defined as.

NULL array(2) { [0]=> string(3) "100" [1]=> string(3) "340" } That is one var. What is the other var?

Thank you very much! Now I know the error.. One of those variables are NULL! When I fix it I think it work! Karl actually, the null is ok I think. The array is wrong - you can't 'add'

an array to a scalar variable, which an integer or null is.

Yes, it is me and arrays again :D $resultat = mysql_query($sql, $tilkobling) or die(mysql_error());

         $antall = mysql_num_rows($resultat);
         for($i = 0; $i < $antall; $i++){
             $rad = mysql_fetch_array($resultat, MYSQL_ASSOC);

and write it tis way can perhaps make someting more correct? For example $variable[$i] ? Karl Not sure what your question is now. But - $rad will contain a single row of values here, all in an array such as $rad['field_name1'],$rad['field_name2'],$rad['field_name3'],.... .
