menuparent im horizontalen CSS Menu funzt nicht

Hallo, ich versuche seit Tagen just2b's horizontales Menu ans laufen zu bringen. #39055
Es tut es auch ganz gut, außer dass die menuparent Funktion nicht greift.
Daher zeigt das Menu dann halt auch nicht den Pfeil an, der anzeigt ob es noch ein Untermenu gibt...
Es wäre wirklich Toll, wenn mir jemand auf Die Sprünge helfen könnte...

Danke!

Emil

Hier meine verschiedenen Codes, das CSS hab ich mal mit angehängt, ist aber 1:1 aus dem Beispiel übernommen:

# Configuring the Auto-Parser for main template:

plugin.tx_automaketemplate_pi1 {
    # Read the template file:
  content = FILE
  content.file = fileadmin/templates/main/rootpage.html
    # Here we define which elements in the HTML that 
    # should be wrapped in subpart-comments:
  elements {
    BODY.all = 1
    BODY.all.subpartMarker = DOCUMENT_BODY
    HEAD.all = 1
    HEAD.all.subpartMarker = DOCUMENT_HEADER
    HEAD.rmTagSections = title
    DIV.all = 1
  }

# Prefix all relative paths with this value:
  relPathPrefix = fileadmin/templates/main/
}




# Main TEMPLATE cObject for the BODY

temp.mainTemplate = TEMPLATE
temp.mainTemplate {
    # Feeding the content from the Auto-parser to the TEMPLATE cObject:
  template =< plugin.tx_automaketemplate_pi1
    # Select only the content between the <body>-tags
  workOnSubpart = DOCUMENT_BODY
  
# Substitute the ###topmenu### subpart with dynamic menu:
#  subparts.nav < temp.MENU

#MENU
subparts.nav = HMENU
subparts.nav {
	special = directory
	special.value = 22
	1 = TMENU
	1 {
		expAll = 1
		wrap = <ul id="nav">|</ul>
		noBlur = 1
		NO = 1
		NO.wrapItemAndSub = <li>|</li>

		IFSUB = 1
		IFSUB.wrapItemAndSub = <li class="menuparent">|</li>
		ACTIFSUB < .IFSUB
	}
	2 < .1	
	2.wrap = <ul>|</ul>

	3 < .2
	4 < .2
}

# Main TEMPLATE cObject for the HEAD

temp.headTemplate = TEMPLATE

temp.headTemplate {

    # Feeding the content from the Auto-parser to the TEMPLATE cObject:

  template =< plugin.tx_automaketemplate_pi1

    # Select only the content between the <head>-tags

  workOnSubpart = DOCUMENT_HEADER

}

# Default PAGE object:

page = PAGE

page.typeNum = 0

# Copying the content from TEMPLATE for <body>-section:

page.10 < temp.mainTemplate

# Copying the content from TEMPLATE for <head>-section:
page.headerData.10  < temp.headTemplate

page {
headerData = COA
headerData.11 = TEXT
headerData.11.value = <script type="text/javascript" src="fileadmin/templates/main/css/menu.js"></script>
     }

	<link rel="stylesheet" type="text/css" href="css/menu.css" />
