[wix-users] error LGHT0204: ICE61: Upgrade.VersionMax cannot be less than Upgrade.VersionMin

[kpeters]

     I have:
     ...
     <?define MaximumUpgradeVersion="214.2.0" ?>
     <?define ProductCode="*" ?>
     <?define ProductVersion="214.3.0" ?>
     ...
     <Upgrade Id="$(var.WrongUpgradeCode)">
       <UpgradeVersion
         Minimum="1.0.0"
         Maximum="$(var.MaximumUpgradeVersion)"
         IncludeMinimum="yes"
         IncludeMaximum="yes"
         Property="WRONGUPGRADECODEPRODUCT" />
     </Upgrade>
     ...

     I receive:

     error LGHT0204: ICE61: Upgrade.VersionMax cannot be less than 
Upgrade.VersionMin (WRONGUPGRADECODEPRODUCT)

     How is "214.3.0" less than "214.2.0" ?

     Am probably way off somewhere....
