If you are trying to append each row to the multi-value token, then you need to create the token prior to the "For Each..." activity, and within the "For Each..." activity, you would modify the token to append the new values to that multi-value token.

You should probably use the "For Each Row" activity instead of the "For Each Value", which will iterate through the rows of the table from the form.

Additionally, the tokens you are pushing into the token when appending to it, should be the tokens from the "For Each Value" activity, not from the original retrieved tokens.

It should look something like this:

Note - you should probably edit your post and change it to a question instead of a discussion, so that when you have a satisfactory response, you can mark it as the answer.
