Single row table with for-each group loop to set variable.

Question

Hi: There is probably a simple answer for this but I have not found it ...
I have a single row table to loop through a group to set a variable holding a running amount. I am not displaying the amount within the table however when I preview the report I see that the table is expanding (adding rows) for each loop.
The single row table has 3 columns.
1st column
<?for-each:AC_GROUP?>
2nd column
<?xdoxslt:set_variable($_XDOCTX,'xAmtVar',xdoxslt:get_variable($_XDOCTX,'xAmtVar')+CURRENT_AMOUNT)?>
3rd column
<?end for-each?>
Should I be using <?for each-group?> or something else. My requirement is to set the value of the variable with the running total but because the loop is adding rows for each value it loops through (even though not displayed), it is moving other areas of the layout off the page.
Hope this makes sense. Thanks in advance.

Answer 1

you can do it many ways.
No need to loop
You can create a variable and put the sum amount directly in that.
<?doxslt:get_variable($_XDOCTX,'xAmtVar',sum(/AC_GROUP/CURRENT_AMOUNT))?>or
loop thru and add like you do.
<?for-each@inlines:AC_GROUP?><?xdoxslt:set_variable($_XDOCTX,'xAmtVar',xdoxslt:get_variable($_XDOCTX,'xAmtVar')+CURRENT_AMOUNT)?><?end for-each?>do give any space or enter character in word between them, just put this in a single form-field will do
But as i said, i would certainly go with first option.
