After creating a Form associated with a table, I discovered that one column is missing.
How to add a missing column into Form.
This is all covered in detail in the LO documentation in Chapter 4 Forms. Basics about creation start on page 5 while adding fields is dealt with starting on page 48.
@Hrbrgr Thanks, but had already given a link previously in another answer. Also there are links available right from the forum - but it appears many don’t look.
Yes, that is the “laziness” of the questioners in this day and age.
Well, the interface in my version (22.214.171.124) is different from that exposed in user’s guide, but finally I have found how to proceed. Thanks.
