Crispy,
The diagnosis/solution for the form problem you describe is going to be
pretty much as we discussed in your post of Nov. 23 - and in the responses
to your post from earlier this afternoon:
Your Form properties should be set as follows:
Allow Additions should be 'Yes'
Allow Deletions should be 'Yes'
Allow Edits should be 'Yes'
RecordSet Type should be 'Dynaset'
And, since you indicate that the record source of your form is a "mix of
tables", you should check to see that the query that is composed of this mix
of tables is, in fact, an Updateable Query. You can do this by opening the
query itself without using the form and attempting to make an edit to any of
the fields in the query. If an edit cannot be made in the query itself,
then it will not be permissible in the form. If your query is not
updateable, then re-thinking your design and the process or objective you
want to complete will be necessary.
