Config.XML Chained Install

[-DC-]

The technet site give this for config.xml
http://technet.microsoft.com/en-us/library/cc179195.aspx#ElementCommand

<Command Path="msiexec.exe" Args="/i \\server\share\my.msi" QuietArg="/q"
ChainPosition="after" Execute="install" Wait="-1"/>



I used the following with out the wait command as there is only one MSI for
now.
<Command Path="msiexec.exe" Args="/i
\\server\Word2007GetStartedTabSetup.msi" QuietArg="/q" ChainPosition="after"
Execute="install"/>


When I run setup.exe with this config.xml file it says that its invalid and
error out the installation... Am I missing somthing here?!?!?!?!??



PLS HELP
