Previous() not working correctly

[Former Member]

Hello!

I've a report with this group structure:

Question Type
 -> Question Block
 -> Question
 -> Compare level

In the compare level there are two possible values: 1 and 2. My body section is hidden for compare_level = 1. The values should be displayed in body section for compare_level = 2 with Previous() but I get zero. If I disable hiding on compare_level = 1 I see the values correct. So why is Previous() not working?

It seems that this error occurs only if I access a field of my datasource with Previous(field). If I access a formula with Previous(formula) which returns the field value it works.

Thanks!
