collection manipulation

[PavelAbakshin]

Hello!  Help me please with loops. The situation is this: on the current i have loop, where I go to another page in the process, there something happens, when I return back to the loop. And if I have several items in the calculation for the collection that the loop is on, this calculation falls with an error that "There is no current line in the collection" What's may be wrong?

Can you put a snapshot of your code ?

Hi Abakshin, You should include a sample of your could to help us understand the issue. I would say the problem is that the collection resets to initial value when the page finish. If you click on the collection twice on the collection properties window comes up, in the bottom left corner there is a check box called : Reset to inital value whenever this page runs But be careful with this, becuase the collection will keep it's value if you opt this out, so you will have to delete the values yourself if needed. I hope this helps!
