@Pat HartmanIf you have to make a comment for each tag you record, then a multi-select combo will be no help to you.
Dear Pat. The relation between comments and tagnumbers is 1 to many. One comment to many tagnumbers.
I cannot publish the supplier document for legal reason but image the comment is for example: "painting color RAL should be RAL1731" and this comment is applied to all the tags listed in the page where the comment is inserted.

Dear Gasman, thank you for your instruction, I will prepare a sample of the mask for the data entry of the tagnumbers and then I will post the photo.
