It's possible that $vCityStateZip is a sequence of more than one item.
 Have a look at its declaration to check what the "as" attribute
contains - I'm guessing it won't be defined correctly, if at all.

Just to speculate some more, I guess you have something like this:

<xsl:variable name="vCityStateZip">
  <xsl:value-of select="city"/>
  <xsl:value-of select="state"/>
  <xsl:value-of select="zip"/>
</xsl:variable>

and you really want:

<xsl:variable name="vCityStateZip"as="xs:string">
  <xsl:value-of>
    <xsl:value-of select="city"/>
    <xsl:value-of select="state"/>
    <xsl:value-of select="zip"/>
  </xsl:value-of>
</xsl:variable>

The former is sequence of several items, the latter is a sequence of one
item.
