Multiple "if()" statements

I have a table with lots of fun information in it. For one of the pages that I am working on, I want to display a list of names based on what is in the DB. My $SQL statement works great and has pulled in values for "first_name," "hs_last_name," and "last_name" in that order. Right now, I am just printing to the screen the results of "first_name (hs_last_name) last_name" but there are two problems with this... The first problem is men's names and unmarried women's names... they will have the same "hs_last_name" and "last_name" so I don't want the duplicate displaying on the page. The second problem is the entry of the word "none" by some of the visitors in place of a "hs_last_name"... obviously I don't want to display this either. The following is the string of "IF()" statements that I am using, but I have an issue with my syntax somewhere because it isn't working the way I want. Any help would be great! if($row[1]="none") { print("<tr>"); print("<td>$row[0] $row[2]</td>"); print("</tr>"); } else if($row[1]=$row[2]) { print("<tr>"); print("<td>$row[0] $row[2]</td>"); print("</tr>"); } else print("<tr>"); print("<td>$row[0] ($row[1]) $row[2]</td>"); print("</tr>");
