[xsl] Trying to define a derived variable from 3 other variables - getti

Why am I getting an error on the following line
                <xsl:variable name="LibrBatchNo" 
select="concat($CurrDateTimeValue,$ POOwnerType,$InvoiceCurrency)"/>   


Error in expression .$LibrBatchNo: Unexpected token $ beyond end of 
expression
           Also getting an error on two defined date fields at top. Trying 
to replace date format defn's with extended date-time functions but hav 
not figured that out yet


Here is my code in my stylesheet

<?xml version="1.0" encoding="UTF-8" ?>
