Without showing us the input form you are making us guess....

	<xsl:starts-with(Module, $sModule)>

there is no xsl:starts-with element, so that will be a synatx error.

You want something like

<xsl:template match="/">
<xsl:for-each select=Sales/Summary[starts-with(Module,$sModule)]">
<xsl:sort select....


assuming Module is a child of Summary
