HI Stephani,
you need to create a static parameter and pass the list of values as ('show', 'not show').
If you place that values in group section, then you need to right click on left side grey area of that section --> Goto 'section expert' --> select 'suppress' condition formula and put the below formula there...
If (balance<100 and {display parameter} = 'not show') then true else false
if the values placed in different sections apply the above steps for each section...
Hope this will suppress balance values based on your requirement...
Thanks & regards,
Naga.
