Saving the EmbededDate which depends on the choice in a looping block.

Hi guys, I have a block that is looping and the number of loops depends on the subject's previous choices. I need to save the choice and the unselect options in the last loop.

However, I do not know how to specify in the embeddedData.

I am guessing the following:

selected = ${q:// e://Field/loopnumber _QID696/ChoiceGroup/UnselectedChoices}'
unselected = ${q:// e://Field/loopnumber _QID696/ChoiceGroup/UnselectedChoices}'

Where ''loopnumber'' is en embeddedData telling me the number of the last loop, which is defined by a previous choice of the subjects.
But it seems that qualtrics does not read a global variable inside a global variable.

Anyone has a good idea?

Many Thanks!

Best,
Rui
