Dynamically retrieving href for static object.
Hi there,

I have an object for which I need it to retrieve the href parameter from a content picker.

I know that the code I need in order to get the URL is as follows:
```
umbraco.library:NiceUrl(number(./data [@alias = 'northRegionLink']))
```
But I am unsure how I would insert this in an (Rather complex - it is inside an image map) object's href.

Is it possible to create a macro and insert it inside the href declaration? If so, how would I do that?

Yes its possible to create a macro to retrieve this link.

to put it in your href you do just that.
```
<a href='<umbraco:macro alias="yourMacroName" source="[#northRegionLink]" runat="server" />'></a>
```
obviously you would need to create a Macro that accepts a parameter source and then do your usual Umbraco Library call to get the link back.

Okay, passing the value to the macro seems to be working fine, but how do I simply output the value of
```
umbraco.library:NiceUrl(linkNode)
```
where linkNode is my parameter?

I have ammended this to;
```
<xsl:value-of select="umbraco.library:NiceUrl(string(/macro/linkNode/node/id))"/>
```
However, I stil recieve a System.OverflowException;
```
System.OverflowException: Value was either too large or too small for an Int32.

just use a
```
<xsl:value-of select="umbraco.library:NiceUrl($linkNode)"/>
```
This assumes that you have created the variable for linkNode.
```
<xsl:variable name="linkNode" select="/macro/linkNode"/>
```

Wrap the niceurl line with an xsl-if like this.
```
<xsl-if test="$linkNode !=''">
<xsl:value-ofselect="umbraco.library:NiceUrl($linkNode)"/>
</xsl:if> 
```
This should sort it for you.
