Still trying to solve this. I have 2 tables, 1 is tbltripNumber from whose data when populated I will create a report. 2nd table tblFromTo which contains 3 fields. 1 is ID, 2 is place names, and 3 is contracted days. This table used for my combo box. when a place name is chosen from combo box a resulting number of contracted days is placed in another field - "Contracted Days" on the form frmTripNumberDurations. This all works fine excet the contracted days doesnt fill in the tblTripNumber but does on the form. Likewise the "Demurrage days" also a correctly computed field shown on the form also does not populate in the tblTripNumber.
This plus the form showing #Name? when ever I visit it the next day after it working fine the previous day are the two problems.
