|        This morning's data:
| 
|        [bobg at box9 ~]$ cat foo
|        <graph caption="Customer: bobgoodwin at wildblue.net"
|        xaxisname="Figures Shown Reflect Data Usage in the Last 30 Days"
|        yAxisName="Data Usage" bgColor="E3ECF6" showGridBg="1"
|        showCanvas="1" numdivlines="4" decimalPrecision="0"
|        zeroPlaneColor="CCCCCC" zeroPlaneAlpha="40" numberSuffix="MB">
|        <set name="Actual Usage Upload" value="1094" color="007CC2"/>
|        <set name="Usage Threshold Upload" value="5000" color="9CA279"/>
|        <set name="Actual Usage Download" value="12012" color="007CC2"/>
|        <set name="Usage Threshold Download" value="17000" color="9CA279"/>
|        </graph>
| 
| 
|        [bobg at box9 ~]$ sed -n '/Actual Usage
|        Download/s/.*value="\([^"]*".*/\1/p' < /home/bobg/foo
|        sed: -e expression #1, char 49: Unmatched ( or \(
| 
|        I thought perhaps a permissions problem?

No, an unmatched bracket in the expression. Try this:

  sed -n '/Actual Usage Download/s/.*value="\([^"]*\)".*/\1/p' < /home/bobg/foo

All on one line, if the above gets folded.
Note the closing \) I've added.

Cheers,
