Re-assigning a variable's value

[Faheemi]

Hi there,

I am very new to XSL. I wanted to do the following:

Assign a variable named "Total_Amount" in the global scope.

Then I loop through each child nodes using

<xsl:for-each select=&quot;RESULTSET/ROW&quot;>

and add the node value of &quot;Amount&quot; to the global &quot;Total_Amount&quot; variable and finally display it as Grand Total at the end.

<xsl:variable name=&quot;Total_Amount&quot;><xsl:value-of select=&quot;$Total_Amount + $Amount&quot;/></xsl:variable>

But the global variable is not being modified. It seems that it creates a local variable with the same name of the global variable.

Also it seems that a variable within the for loop is not global even within each iteration of the loop.

I have no idea how to work this around.
Please shed some lights on my issue.

Thanks a lot.

Hi Hameed,

Variables in XSL can not be reassigned, thus meaning that once you've assigned a value to a variable, you can't change it anymore.

Try to use the sum() function instead.

Good luck!

Thanks Jordi,

I was finally managed to use sum() function to get the result.
