Question for If condition with variables

Question

HI Expert, there is a question need your kind help. I am doing the report based on the RTF, and logic is I init the variable 'INCOME' firstly, and then set the value of the varibale in the loop, then I need check this variable by if condition, the logic is simple, but it can not work and the setting value seems cannot be effective in if condition(cannot do print)
Code list as below:
<?xdoxslt:set_variable($_XDOCTX,'INCOME', 0)?>
<?for-each:GLB_ARCH_PR?><?sort:current-group()/GLB_PAY_ARCH_EE_INFO/PERSON_ID;'ascending';data-type='text'?>
<?for-each-group:GLB_PAY_ARCH_PR_TAX_DEDUCTIONS;./SECONDARY_BASE_CLASS_NAME?>
<?xdoxslt:set_variable($_XDOCTX,'INCOME', 123)?>
<?if: xdoxslt:get_variable($_XDOCTX,'INCOME') > 0?>
.....// print something
<?end if?>
<?end for-each?>
<?end for-each-group?>
In addtion, the first line is in a cell of table, and other lines(setting variable's value and if condition) in another cell.
I guess the variable can not be set and then be checked by if in the same loop(or same cell)? If I do set_variable outsides the loop, the logic can work, could you please tell me if my guess is right? and provide some solution for this.
Thanks a lot!

Thank your feedback in forums for Oracle RTF template questions.
In fact, I found if the variables value setting and if condition in same cell, the value setting always be not effect before the if condition. So if you want set the value firstly, then do if condition. In this case, you cannot get your logic target.
So I guess if the variables value setting and variable if condition in same cell, the execution sequence can not be fixed, or if condition always do first than other operation?
I have done a test to confirm this, I have set the value as 1 for initiation, and if condition is more than 0, so every row can be display. At this case, I modified the value setting as
<? if: xdoxslt:get_variable($_XDOCTX,'Index') = 3 ?>
<? xdoxslt:set_variable($_XDOCTX,'INCOME', 0)?>
<?end if?>
<? if: xdoxslt:get_variable($_XDOCTX,'Index') != 3 ?>
<? xdoxslt:set_variable($_XDOCTX,'INCOME', 1)?>
<?end if?>
That means the variable should be set as 0 when row 3, and that row should not be displayed, but in fact all rows displayed.
My target logic just is do value setting by some logic every rows, and then decide show this row or not by the value, what's more, I have to set them in same cell for loop limitation.
I hope you can find any solutions for this.
