I'm struggling to get my head around using expressions and outputting results in a report format at the end of questions for the user who fills it in - the documentation is either out of date or very high level.
What I need is a very simple step by step tutorial that shows the logic set up with a few questions. "If this question chosen then output this result at end of the form."
Another solution might be importing an existing form where some of the expression and report features were included - I noticed that was possible.
There are loads of examples in the documentation with sample surveys.
Out of date can't really be because there have been very little changes to the Expression Manager since it has been implemented. Only because the screenshots might not be exactly as your interface, the information should still be valid.
Expression manager is quite mighty and "a simple step by step tutorial" will not do it.
