Help with a Command script

Question

Hello,
Awhile back someone wrote the following script for me. The
idea was to make a comman that would allow me to reduce an image
down to 400 pixel width without loss of scale. I want to have a
similiar command that will reduce a large image down to 400 pilel
height without loss of scale. I fiddled with the command for width
but can't get it to work for height. Can I get some help rewriting
the following command to work for 400 pixel height? Thanks.
// User Variables
var width = 400;
// Command
var dom = fw.getDocumentDOM();
var scale = width/dom.width;
var height = dom.height * scale;
dom.setDocumentImageSize({left:dom.left, top:dom.top,
right:dom.left+width, bottom:dom.top+height},
{pixelsPerUnit:dom.resolution, units:dom.resolutionUnits});

The word "scale" is critical, but I switching did not help.
Just switch the variables word for word. Height for width and
width for
height.
// User Variables
var width = 400;
// Command
var dom = fw.getDocumentDOM();
var scale = width/dom.width;
var height = dom.height * scale;
dom.setDocumentImageSize({left:dom.left, top:dom.top,
right:dom.left+width,
bottom:dom.top+height}, {pixelsPerUnit:dom.resolution,
units:dom.resolutionUnits});
// User Variables
var height = 400;
// Command
var dom = fw.getDocumentDOM();
var scale = height/dom.height;
var width = dom.width * scale;
dom.setDocumentImageSize({left:dom.left, top:dom.top,
right:dom.left+width,
bottom:dom.top+height}, {pixelsPerUnit:dom.resolution,
units:dom.resolutionUnits});
Once you see this script, it's not hard to see what it is
doing.
This is the Fireworks generated script scaling just the
height of an
image to 400 px from 640x480 px.
fw.getDocumentDOM()
.scaleSelection(0.83281248807907104, 0.83333333333333337,
"autoTrimImages transformAttributes");
This works on all 640x480 images. Throw in a 700x480 and it
won't.
I'm assuming, very few people in here (myself included),
would be able
to transform this into something that would account for
varying widths
as senocular did.
