Access form entry - 'locked' field?

 It's enabled and not locked, so I'm not certain what else to check?

If the control's properties is not set as Locked and Enabled = False but it appears that it is. I guess probably some VBA codes have changed the control properties dynamically?

hence, try verify if there's any codes in Form_Load or Form_Current event that changed the control's property?

I suppose I should point out, I'm using the contact template to build everything from.  This was a field that I changed to multi-select.
There is some slight vba code, but nothing that would prevent me from selecting data in this field.

1.  Check the AllowEdits property of the form is true
2.  Check that the data the form is based on is editable.   Open it's recordsource directly and see if you can edit the fields.

And welcome back to Access....haven't seen your name in quite some time.

Thanks Jim.
I neglected also to mention the version!  Sorry about that... O365 (v 2004 - build 12730.20236).

For AllowEdits, I can edit other fields, so even though I can't locate that property, I'm assuming it's true?
I have Allow Form view, datasheet & layout view (bookends are set to yes).

In the datasource, the field is set to a short text data type.  Since this is built off of the contacts template, I do have an order by field that is probably invalid, so I removed that. I can edit outside of the form, no problem.
The lookup tab has allow multiple values, limit to list, allow value list edits all set to Yes.

Still unable to edit that one and only field. 

Excellent.  

Jim.
