Hi
Can’t enter data in a form after creating a relationship between 2 tables with a primary key.what should I do?
Hello,
Post a sample. Have no idea what your problem is based upon text.
Do so by editing your question. Do not use an answer.
If it helps, there is a simple sample in my answer on this post → Database showing two tables but problem with the marriage table
There is also the LO documentation → LibreOffice Base Guide. Chapter 4 is about Forms. It has a section on Main forms and subforms.
