Hi,
I would like to add a String called 'FX' before the display
of an element.

I am currently using this :

<xsl:with-param name="value">
<xsl:value-of select="description"/>

I would like to append the value of 'FX' in front of the value being displayed by 'description'.

ie: FX + value of description.

Please can some tell me how to do this?

Done.
Used the concat functionality.
Thanks

select="concat('FX', description)"
