Re: Scope of Local Variables?

Hello,

Using the MSXML 4 parser, as well as Instant Saxon 6.5.2 I'm getting an
error of "variable may be out of scope" when trying to use a variable
locally.  Listed below are my XML and XSLT files..... am I defining the
variables incorrectly?  I'm attempting to call the variables in a sibling.
Please help!
