Let's say 10 datasets are shown and 1 of them is broken (with answers outside the allowable tolerance). After adjusting the dataset wildcard and pushing save, the answer sets should be recalculated but they are not. Therefore it may seem impossible to save the adjusted dataset. There should be a button to refresh the displayed calculations (on the third page) so that the question can be saved without error. Adjusting the tolerance on the third page is also problematic as adjustments cannot be applied to refresh the displayed results. It is also impossible to change the calculated formulas without using the back button, but that takes the displayed question state to a point that does not reflect its saved state either.

Thanks again to your extensive manipulations of calculated questions.
Effectively there is a problem that I recently trace back about updating.
I am working on this and other related issues (MDL-37744).
Thanks for the response Pierre. I do like using the calculated question type. Thanks for creating it and improving it.
