Nikolaev Artem's final test (think)

Hey there!

Thanks for your message. I get that you're having trouble saving your worksheet.

First off, please make sure you've finished adding all the pieces. For instance, if you're doing a drag-and-drop, be sure to complete the whole drag and drop combo before trying to save.

A good tip is to add just a few elements, save, and then add the rest using the edit elements section.

I hope this helps, please let us know if you have any questions.
