Using a variable outside of the block it has been incremented

Question

Hello everyone,
I came across a scenario where in I am having to use a variable (for summing up), outside of the block within which it has been incremented. Its something like below:
-------------- Header section of MS Word RTF (repeats for every page) -----------------------
For Each Header
<?xdoxslt:set_variable($_XDOCTX, 'TotalTax', 0)?>
-------------- Body section of MS Word RTF -----------------------
<?start:body?>
Lines Group
Increment TotalTax for each loop
End Lines Group
<?end body?>
-------------- Footer section of MS Word RTF (repeats for every page)-----------------------
<?xdoxslt:get_variable($_XDOCTX, 'TotalTax')?>
End For Each Group
---------------------------- End of template ----------------------------
The varaible 'TotalTax' is being declared in the header, incremented within the Body and is being used in the footer section. For the above mentioned syntax, the value being displayed for TotalTax is '0', i.e the value for which it has been defaulted while declaration.
Can someone please help me in getting it fixed such that TotalTax would display the value it was assigned in the Body rather than '0'.
Thanks,

Hello and thank you for responding.  I checked out the link you provided; however, my problem is not reviwed there.
I am setting a variable inside a <?start:body?>.  Inside the body are several loops - which is fine.  But it ends with <?end body?>.  If I reference my variable BEFORE <?end body?> it retains it's value from the calculations within the program.  But if I try to use the variable AFTER the <?end body?>, it give me an error "NULL" value or similar.
Any thoughts?
