[quote="ajb":1uu8jzv3]You can't use select field for user table as it's not a recordset.
You've got two options.
1. Create text/int field, and use QFfield callback to create select field with proper logins. You can get login as a value stored in database. Or user id - I think it's a better idea. (text/int depends on this choice)
2. Use CRM_Contacts_RBO_Contact field type with crits callback. You'll see only specific contacts. You'll get contact id as a value.
I suggest second one as you'll get more options and it's simpler.
Pick one and try to do this. I can help you then.[/quote:1uu8jzv3]
Thanks ajb. Ive opted by the top one and i managed to get it working.
Cheers 😃
