In step 2
Change "<a href="default.htm" onClick="return clickreturnvalue()" onMouseover="dropdownmenu(this, event, menu1, '150px')" onMouseout="delayhidemenu()">Web Design</a> |"
To "<a href="webdesign.php" onMouseover="dropdownmenu(this, event, menu1, '150px')" onMouseout="delayhidemenu()">Web Design</a> |"
Im not certain now but it looks like it should work to me...
