Regular expression replacement in SED.

["Robert Speed" <nospam [at] Viclabs.co.uk>]

Quick question for any sed people;

I'm trying to perform a regular expression replacement from sed
but by passing params within a bash script.
However, I'm a tad stuck at how to force the command line
to stop interpreting white space literally.

ie.
if (from the cli) I ;
sed 's/%NAME%/Fred Flintstone/' letterin > letterout

I can replace all instances of %NAME% in letterin with
Fred Flintstone and send the output to letterout.

Fine, fair enough.
The problem I have now is how to automate this from within a shell 
script.

So, what I have in the script is the following;

SedCommand=\'s\/%NAME%\/$Recipient\/\'
echo sed $SedCommand $InputDoc \> $DocToSend
sed $SedCommand $InputDoc > $DocToSend

(Note, that they're not Vs in there, but escaped \ !)
Now this is giving the output;

sed 's/%NAME%/Robert Speed/' letter2 > form_rms.doc
sed: 's/%NAME%/Robert is not a recognized function.

The key point here is that the command line is interpreting the 
space in the variable $Recipient literally.
The variable has previously been read in from another file, and so
will never be the same for each iteration. 

(Now, this is just one step within the script, there's loads of other 
stuff going on, it's just that this bit is as crucial as any other).

I've tried 'escaping' the name in the source datafile (where the 
recipients name is coming from), but to no avail...

Anyone any ideas ???
