@ChristineTombleson1 Would you be willing to share your process? I'm trying to do the same, and I'm hitting a wall on integrating the two apps.
To the OP, FieldMaps designer is intuitive and easy to use, but as was suggested, if your form information is complicated, you may want to integrate Survey123 for the form usage. The tables that come out of FieldMaps can get huge if you are trying to collect archaeological data, which leads to large data tables to deal with on the back end.
