I'm having a problem with subforms. I've gone back to Expert 3 and tried again from scratch and I still don't get the Master and Child Links in the Properties Sheet. Whether I use the Subform from the Tool Box or just drag my subform onto my form, when I click on Property Sheet, Data shows the source and below it "Dynaset". Sorry, I'm also having trouble with field names because I'm using a Portuguese version of Access 2013. On the other hand, the subforms are working correctly, so...could this be a change from Access 2010 to Access 2013?
