I'm trying to create a slideshow using xslt, butI have a problem
passing the numeric value height to the macro

       <umbraco:Macro MediaRoot="number([#MediaRoot])" 
                         height="number([#height])" 
                         width="[#width]" 
                         class="[#class]" 
                         Alias="SlideshowImagesList" 
                         runat="server">
          </umbraco:Macro>

I get this error . also without the number()

Parser Error Message: Cannot create an object of type 'System.Web.UI.WebControls.Unit' from its string representation 'number([#height])' for the 'Height' property.

Height is defined as number in the macro - the input comes from a
document where it is defined as numeric.

What is wrong here?

Hi Paul,

You're using an XPath function (number()) within an ASP.NET tag - that won't work.

You can do the cast within the XSLT file if needed (typically not needed), e.g.:
```
<xsl:variable name="mediaRoot" select="number(/macro/MediaRoot)" />
```

Oh - my bad... forgot one very annoying thing: You can't use "width" or "height" as names for Macro parameters because they clash with some built in .NET stuff.

Use with a prefix, like "imgWidth" and "imgHeight" and it'll work (still shouldn't use number() within the attributes, though)

Thanks Chriztian

That was the solution!

          <umbraco:Macro MediaRoot="[#MediaRoot]" 
                         ImageHeight="[#height]" 
                         ImageWidth="[#width]" 
                         Class="[#class]" 
                         Alias="SlideshowImagesList" 
                         runat="server">
          </umbraco:Macro>
