Flash MX - Flashlevel nav - dynamically changing thumb width?

Hi all,

I am using Voetsjoeba’s creation of flashlevels navigation system for my own website, but Im having some trouble with some AS, which I hope you will be able to clear up for me.

In the AS, Voetsjoeba has made the width of the thumbs static to 55px.
Id like this to be dynamic, so that thumbs can be different widths.
ALSO I would like the thumbOverAnim to follow this width of the thumb image loaded, but I cannot seem to get this created.

Id appreciate all the help I can get.
Im sure its quite simple.

supposedly just use the with the MC of the image gets after loading the thumb, but I cannot get this AS to work.

ActionScript Code:

[FONT=Courier New][LEFT]spacing = [COLOR=#000080]5[/COLOR];</p>
<p>boot = [COLOR=#000000]function[/COLOR] COLOR=#000000[/COLOR] [COLOR=#000000]{[/COLOR]</p>
<p> [COLOR=#0000ff]for[/COLOR] [COLOR=#000000]([/COLOR][COLOR=#000000]var[/COLOR] i = [COLOR=#000080]0[/COLOR]; i<images.[COLOR=#0000ff]length[/COLOR]; i++[COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]</p>
<p> mc = container.[COLOR=#0000ff]attachMovie[/COLOR][COLOR=#000000]([/COLOR][COLOR=#ff0000]“thumbMC”[/COLOR], [COLOR=#ff0000]“thumb”[/COLOR]+i, i[COLOR=#000000])[/COLOR];</p>
<p>[COLOR=#808080]//The 55 is what Id like to be made dynamic</p>[/COLOR]
<p> mc.[COLOR=#0000ff]_x[/COLOR] = i*COLOR=#000000[/COLOR];</p>
<p> mc.[COLOR=#000080]path[/COLOR] = images[COLOR=#000000][[/COLOR]i[COLOR=#000000]][/COLOR].[COLOR=#000080]path[/COLOR];</p>
<p> mc.[COLOR=#000080]link[/COLOR] = images[COLOR=#000000][[/COLOR]i[COLOR=#000000]][/COLOR].[COLOR=#000080]link[/COLOR];</p>

<p>[COLOR=#808080]//Over is the instance name ot the animation that comes over the thumbImage. This is my pathetic attempt, which doesn’t work</p>[/COLOR]
<p> mc.[COLOR=#000080]over[/COLOR].[COLOR=#0000ff]_width[/COLOR] = mc.[COLOR=#0000ff]_width[/COLOR];</p>
