Hi All I have two tables access DB Table one – Patients’ bio data Table two – Referral Data Referral table collects data such as – date of referral, time, Reason/s for referral etc I created One to many relationship – as same pt can get referred many times over months and years. Based on this, I created a Registration form with Referral details form as the Sub form. For the reasons for referral field – I created look up/List box. This box contains reasons, such as Anxiety, Depression, Dementia … etc I put about 20 of most common reasons. At the point of registration – Admin team put patient’s personal details in the main form and in the sub form under Reasons for referral, user select A reason or reasons by ticking the box. My Problem: At the point of putting Referral date, Time.. etc The Referral Reason field get Automatically update it self (without the user selecting any options) . And the Automatic update happened with any random reason (computer select a random reason) I checked whether I have put any Default values – and the answer is NO Then on table level – I deactivated Must complete option from Yes to NO – still no change Its like a ghost ticking a random reason for referral before the user get even near to the field Any advise ??? Thanks
