Hi Curtis,
I understand you followed the workshop and encountered problem pull the information from submission form onto approval form.
I have looked through the workshop, since you can get the information, I would like to know what the problem is, does it retrieve an incorrect value?
Based on my understanding, the problem should be caused when fetching the request data. You can verify if the final form load rule is shown as following:
If not, I suggest you follow the workshop to recreate the workflow to see if it can works fine.
Thanks,
Evan Zhang
