Group header with print when expression IREPORT

[lip_bahia]

 I have a group X and want the header of this group is written only if the value of a variable sum is not equal to 0 in this way:

 

new BigDecimal (0). compareTo ($ V { TOTAL_EMP_UO})! = 0    | | New BigDecimal (0). CompareTo ($ V { TOTAL_LIQ_UO})! = 0    | | New BigDecimal (0). CompareTo ($ V { TOTAL_PAG_UO})! = 0[/code]

 

But when I put this condition in Print when group header he did not write the header, it is as if the variable was always 0 before the group.

 

But the group footer has the same condition and is writen.

 

How do I fix this?
