Good morning,
I've 3 tables (tbl_Medical, tbl_Employee & reference table tbl_EmpMed).
fMedical in tbl_Medical is the standard frequency of each medical examination but they can be personalized if there is a need.
Frequency in tbl_Emplyee is the personalized frequency for each Employee.

My goal is that if the Button A in tbl_Employee is true the personalized frequency is used to create the next deadline. If the button is false the standard frequency is used.

I create the deadline in my query1 with A1: DatAdd("m";[Frequency];[mDate])


Best regads
Georg

That's a checkbox for a Yes/No field, not a button.

DateAdd("m"; IIf([A], [Frequency], [fMedical]); [mDate])

what is ID on tbl_Medical? is it autonumber?
if it is then, if employee has same Med_ID, mdate will keep on adding 3 months when A field is clicked.
