Is concatenation of numbers is possible in the loop??

Question

Hi All,
We have used the following code for our requirement in the rtf template.Here AMOUNT is a field name.But the following code is erroring out.
<?xdoxslt:set_variable($_XDOCTX, 'A',1)?>
<?xdoxslt:set_variable($_XDOCTX, 'Payout',0)?>
<?xdoxslt:set_variable($_XDOCTX, 'Total',0)?>
For-each:G_1
<?choose:?>
<?when:A < B?>
<?xdoxslt:set_variable($_XDOCTX, 'Payout',AMOUNT || '+')?>
<?xdoxslt:set_variable($_XDOCTX, 'Total',AMOUNT+xdoxslt:get_variable($_XDOCTX,'Total'))?>
<?end when?>
<?otherwise:?>
<?xdoxslt:set_variable($_XDOCTX, 'Payout',AMOUNT || 'or')?>
<?xdoxslt:set_variable($_XDOCTX, 'Total',AMOUNT+ xdoxslt:get_variable($_XDOCTX,'Total'))?> <?end otherwise?><?end choose?>
<?xdoxslt:set_variable($_XDOCTX, 'A', xdoxslt:get_variable($_XDOCTX, 'A') + 1)?>
end G_1
SUM=<?xdoxslt:get_variable($_XDOCTX, 'Payout')?><?xdoxslt:get_variable($_XDOCTX, 'Total')?>
output should be such that
SUM=1000+2000+3000 or 6000.
Please suggest some ideas to implement the above.
Thanks in Advance.

Hi All,
We got the answer and it worked fine for us.
<?xdoxslt:set_variable($_XDOCTX, 'Payout', concat(AMOUNT,'+'))?>
<?xdoxslt:set_variable($_XDOCTX, 'Payout', concat(AMOUNT,'or'))?>
We can use the readymade function concat() for concatenation of anything.
