select parameter causing errors

I want to display an image from a media picker, my document type has several media pickers defined and I would like to use the same macro to dislplay the image for each one. I have a macro parameter for alias called propertyAlias which I use to pass in the name of the media picker. But the xslt does not like the variable being used, see:  Unexpected token '$' in the expression what am I doing wrong please?

  <xsl:param name="currentPage"/>
  <xsl:variable name="propertyAlias" select="//macro/propertyAlias" />

  <xsl:template match="/">

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

  <xsl:variable name="media" select="umbraco.library:GetMedia($currentPage/$propertyAlias, 0)/umbracoFile" />
  <xsl:if test="$media">

  <img src="{$media}"  />

</xsl:if>


  </xsl:template>

Hi Andrew,

May be this will help you, i havent tested it but i think it should get you workin

<xsl:param name="currentPage"/>
    <xsl:variable name="propertyAlias" select="macro/propertyAlias" />
  
    <xsl:template match="/">
         <xsl:apply-templates select="$currentPage/TestImg" />
     </xsl:template> 

<xsl:template match="TestImg">
        <xsl:variable name="media" select="umbraco.library:GetMedia(., false())" />
        <xsl:if test="$propertyAlias">
                <img src="{$media}"/>
        </xsl:if>
</xsl:template>

Hi,

To fix that error you should remove the second $ sign from $currentPage/$propertyAlias

If you want to use a variable field name, you can do:
```
$currentPage/* [not(@isDoc)][name() = $propertyAlias]
```
Also, if you get more errors (value too small...) you might need to wrap the GetMedia call in a test to make sure you have a value, ie:
```
<xsl:if test="$currentPage/* [not(@isDoc)][name() = $propertyAlias] &gt; 0">
....
</xsl:if>
```
