I am having a difficult time trying to do something that seems like it should be really easy to do. I basically want to multiply 2 numbers in a node and then sum the total of those numbers for all the nodes. Here is the XSLT code I have tried.

<xsl:value-of select="sum(Parts/Part/Quantity * Parts/Part/Rate)"/>

This code results in an error that says "Argument 1 of function sum cannot be converted to a node set."

Does anyone have an idea of what is wrong or how I can accomplish what I am trying to do?

xslt xslt-1.0 xslt-2.0
