I need to do some simple arithmetic on variables.

xt keeps giving syntax errors, 

 <xsl:variable name="xval" select="@x-coord * 2.29"/> seems OK

but

 <xsl:variable name="x2" select="$xval+($xbox / 2)"/> gives the error
node test expected.

I've also tried 

 <xsl:variable name="x2" ><xsl:value-of select ="$xval+($xbox /
2)"/></xsl:variable>

with the same result.

Ken H (for once) doesn't seem to give such an example.


Any help appreciated please, I'm stuck on this one.

regards, DaveP
