Can you please change your xml to this format:
<?xml version="1.0" encoding="UTF-8"?>
<data>
    <set>
        <months>1/1/2008</months>
        <cash>50500</cash>
        <stocks>198192</stocks>
        <retirement>130101</retirement>
        <home>75000</home>
        <other>19148</other>
        <assets>472941</assets>
    </set>
    <set>
        <months>2/1/2008</months>
        <cash>51000</cash>
        <stocks>201042</stocks>
        <retirement>135000</retirement>
        <home>75300</home>
        <other>19148</other>
        <assets>481590</assets>
    </set>
    <set>
        <months>3/1/2008</months>
        <cash>51550</cash>
        <stocks>206510</stocks>
        <retirement>13700</retirement>
        <home>75600</home>
        <other>19348</other>
        <assets>490008</assets>
    </set>
</data>

Now update the function xmlHandler() to this:
<?xml version="1.0" encoding="UTF-8"?>
<data>
    <set>
        <months>1/1/2008</months>
        <cash>50500</cash>
        <stocks>198192</stocks>
        <retirement>130101</retirement>
        <home>75000</home>
        <other>19148</other>
        <assets>472941</assets>
    </set>
    <set>
        <months>2/1/2008</months>
        <cash>51000</cash>
        <stocks>201042</stocks>
        <retirement>135000</retirement>
        <home>75300</home>
        <other>19148</other>
        <assets>481590</assets>
    </set>
    <set>
        <months>3/1/2008</months>
        <cash>51550</cash>
        <stocks>206510</stocks>
        <retirement>13700</retirement>
        <home>75600</home>
        <other>19348</other>
        <assets>490008</assets>
    </set>
</data>

srv might be a HTTP Handler for fetching the xml data which is missing,

So add a HTTP handler with the id as srv, and the source path to that of the xml.

Also keep the srv.send in where it was and you should be done.

Try this way instead of the model:
<mx:HTTPService id="srv" resultFormat="e4x" result="xmlHandler(event)" />

Add this:
 
<mx:HTTPService id="srv" resultFormat="e4x" result="xmlHandler(event)" fault="onFault(event)" useProxy="false"/>

private function onFault(event:FaultEvent):void{
    //on error
}

Parse error: 'private function onFault(event:FaultEvent):void{//on error}

private function onFault(event:FaultEvent):void{
//on error
}

This is a function and should be in script tag, place this below the xmlHandler() function.

Rest is fine

The process is correct, just check whether the chartInfo object is compatible as the ColumnChart dataprovider. I will try to check your code today and will update you.
