I think you are mixing two things.
In the output configuration, there is a tab named Draft IDs. If you select a column there, the add-on will insert IDs of created Gmail drafts into that column.
And this is a required setting for Merge to Draft and Draft to Send modes.
Then you can, optionally, configure timestamps, and the add-on will insert timestamps into selected columns.
For the QR code. Let's say you have a merge field in your template {{QR}} and you have a column ID card in your sheet.
And you want to encode values from the ID card column as QR codes and place them where the {{QR}} merge field is.
Then you need to map the merge field to a column in the mapping editor and make sure you select option Merge as QR Code.
The source column will be ID Card.
Know the add-on knows that you want to encode those values from the source column as QR codes.
Hi -
Yes, I was using Merge to Draft. I had an ID column on my Google Sheets, but had chosen the default "Do not insert" in the output configuration. I've now changed the output configuration to ask it to insert the ID in the ID column, and it worked (except it doesn't actually insert an ID number anywhere on the sheet. It does insert a time stamp, which is great because the error I was getting last month was regarding time zone (nothing seemed to work to fix that from my end - have you tweaked it?)). So the ID card (with a nice image, yay!) comes through in an email.
What I am not able to get is a QR code. I thought I had it set up correctly, but no code appears on the card. Once again I must be missing a step in my set-up?
Thanks again for your time,
Sylvia
