Hi web not,
your XSLT has been written as if XSLT were a procedural language like C or Java; but in XSLT variables are not re-assignable, and its value must be computed using node sets.

For instance, you could replace the

<xsl:value-of select="$numLink"/>

with a call to

<xsl:value-of select="count(//*[local-name()='item'])"/>

Also, you might investigate the position() function,
and xsl:number.
