Barcodes With Data From Multiple Sources フォローする

I'm having an issue with a label I'm trying to create.

I'm currently recreating all of our existing labels that were used in LabelMatrix, and I've found a label that uses a barcode that pulls data from 3 different sources in the label at once.

I've found how to make the barcode pull the data from one of the three fields in the label, but not all three. Can anyone point me in the right direction?
Ta!
