function problem

I have a function below which populates a select list, based on the query string and the field name. It then prints a string: function populate_selects($query_name, $db_field, $link, $string) { $result = mysql_query($query_name, $link) or die ("Could not execute query."); while ($columns = mysql_fetch_array($result)) { $column = $columns[$db_field]; global $option_block; $option_block .= "<OPTION name='vendor1' value=\"$column\">$column</OPTION>\n"; } print $string; } Part of the string that is printed in $string is the $option_block which is in the function. There seems to be some problem with scope here. I made the $option_block variable global but it still won't print. I have tested that the $column field is being populated and it is, so I believe that it must be the $option_block part that isn't working. Does anyone have any suggestions?
