could someone show me how to hook xtaskbar?

I have this in xlabel:
;*Label xtasklabel
;xtasklabeladdtogroup 100
;xTasklabelX 157
;xTasklabelY -28
;xTasklabelwidth 755
;*xTasklabelModuleHook !xtaskbarhook
(I remove the comment tabs when I am trying to get it to work).

And here is my xtaskbar config:
;xtaskbarloadinbox (not commented when trying to get it to work.)
xTaskbarX 157
xTaskbarY -28
xTaskbarAlwaysOntop
;xTaskbarUseGrouping
xTaskbarWidth 755
xTaskbarHeight 28
xTaskbarImage "bar.png"
xTaskbarnormalbuttonImage "button.png"
xTaskbarActiveButtonImage "abutton.png"
xTaskbarFont "Tahoma"
xTaskbarNormalFontBold "True"
xTaskbarActiveFontBold "True"
xTaskbarMinimizedFontBold "True"
xTaskbarFlashingFontBold "True"
xTaskbarFontHeight "13'
xTaskbarFontColor "CDCDCD"
xTaskbarActiveFontColor "ffffff"
xTaskbarIconX 8
xTaskbarIconY 6
xTaskbarIconSize 16
xTaskBarMaxButtonWidth 250
;xTaskBarMinButtonWidth 150
xTaskbarFontLeftBorder 30
xTaskbarFontRightBorder 3
xTaskbarAlphaFade
;xtaskbarButtonXSpacing 1

Thanks.
