I shall assume your template <xsl:template name="runStrPad"> is working 
fine.. Except you are having some trouble setting variables.. From your XSLT, 
it seems you have XML something like this..
<root>
  <foo></foo>
  <myElement></myElement>
  <myElement></myElement>
   .....
</root>

Probably you need to write your XSLT as ..
<xsl:template match="/root">
  <xsl:for-each select="myElement">
       <xsl:variable name="padFoo">
           <xsl:call-template name="runStrPad">
	<xsl:with-param name="string" select="."/>
	<xsl:with-param name="length" select="16"/>
           </xsl:call-template>
       </xsl:variable>
       <xsl:value-of select="$padFoo"/>
  </xsl:for-each>
</xsl:template>

<xsl:template name="runStrPad">
  .......
</xsl:template>

If you can post your XML and the desired output, I can probably suggest 
something accurate..
