Control the visibility of the skin

Is it possible to control the visibility of the skin with AS3?

Hello Claus,
This is my skin xml :
<krpano>

<display movequality10="BEST" stillquality10="BEST" />

<layer name="buttons" keep="true" url="%SWFPATH%/plugins/textfield.swf" align="rightbottom" width="252" height="50" y="0"
background="true" backgroundcolor="0x0F0F0F" backgroundalpha="0.95"

>
<layer name="line" keep="true" url="%SWFPATH%/plugins/textfield.swf" align="bottom" width="10" height="50" y="0" x="-152"
background="true" backgroundcolor="0x174B5F" backgroundalpha="0.95"/>

<layer name="left" url="vtourskin.png" scale="0.5" align="lefttop" x="10" y="6" crop="0|192|64|64" onovercrop="0|383|64|64" ondowncrop="0|383|64|64" ondown="set(hlookat_moveforce,-1);" onup="buttonglow(null);set(hlookat_moveforce,0);" />
<layer name="right" url="vtourskin.png" scale="0.5" align="lefttop" x="50" y="6" crop="64|192|64|64" onovercrop="64|383|64|64" ondowncrop="64|383|64|64" ondown="set(hlookat_moveforce,+1);" onup="buttonglow(null);set(hlookat_moveforce,0);" />
<layer name="up" url="vtourskin.png" scale="0.5" align="lefttop" x="90" y="6" crop="0|256|64|64" onovercrop="0|447|64|64" ondowncrop="0|447|64|64" ondown="set(vlookat_moveforce,-1);" onup="buttonglow(null);set(vlookat_moveforce,0);" />
<layer name="down" url="vtourskin.png" scale="0.5" align="lefttop" x="130" y="6" crop="64|256|64|64" onovercrop="64|447|64|64" ondowncrop="64|447|64|64" ondown="set(vlookat_moveforce,+1);" onup="buttonglow(null);set(vlookat_moveforce,0);" />
<layer name="in" url="vtourskin.png" scale="0.5" align="lefttop" x="170" y="6" crop="0|320|64|64" onovercrop="0|511|64|64" ondowncrop="0|511|64|64" ondown="set(fov_moveforce,-1);" onup="buttonglow(null);set(fov_moveforce,0);" />
<layer name="out" url="vtourskin.png" scale="0.5" align="lefttop" x="210" y="6" crop="64|320|64|64" onovercrop="64|511|64|64" ondowncrop="64|511|64|64" ondown="set(fov_moveforce,+1);" onup="buttonglow(null);set(fov_moveforce,0);" />
</layer>

<layer name="buttons" width="295" devices="flash">
<layer name="openfs" url="vtourskin.png" scale="0.5" align="lefttop" x="250" y="6" crop="0|576|64|64" onovercrop="0|646|64|64" ondowncrop="0|646|64|64" onclick="set(fullscreen,true);" visible="true" />
<layer name="closefs" url="vtourskin.png" scale="0.5" align="lefttop" x="250" y="6" crop="64|576|64|64" onovercrop="64|646|64|64" ondowncrop="64|646|64|64" onclick="set(fullscreen,false);" visible="false" />
</layer>

<events name="buttonevents" keep="true" devices="flash"
onenterfullscreen="set(layer[openfs].visible,false); set(layer[closefs].visible,true);"
onexitfullscreen ="set(layer[openfs].visible,true); set(layer[closefs].visible,false);"
/>

</krpano>
Is it possible to tell me how can I GET the layer "buttons" in order to control its visibility?
Many thanks for your quick reply,

Unfortunatelly "Cannot access a property or method of a null object reference" is the result. Why is Null?

Yes!! You are right! Works fine now.
