Default how to handle meter readings

You would generally use an unbound combo box for searching. I can't tell if
you have done that, so I'm mentioning it. You say that part is working OK,
so I assume you have this set up correctly.

The subform is in a "box" on the main form. The box is the subform control.
Be sure its Link Child and Link Master properties are set to the linking
fields. To view the subform control property sheet, click the subform to
select it, then click View Properties. Be sure you are looking at the
control properties, which will be labeled something like Subform/Subreport:
ControlName. Click the three dots next to Link Child or Link Master. Access
will probably select the correct fields if the tables are properly related.

[MeterNumber];

the record source for the main form is ElectricityMeter

on the sub form the source object is MeterReading
link child and master are ElectricityMeterID

the ElectricityMeter table has
ElectricityMeterID (link field)
MeterNumber
BuildingID
LocationID

the MeterReading table has
MeterReadingID
ElectricityMeterID (link field)
ReadingDate
PeakReading
OffPeakReading

linked with enforced referential integrity

so you select the meter number from the combo box, fill in the date and
readings - all good except its not picking up the ElectricityMeterID in the
MeterReading table

what am i missing?

If you have a meter table and a related readings table, with a form and
subform for data entry, you can use an unbound combo box on the main form to

Default how to handle meter readings

I've used an unbound combo box and it works but the meter number i select is
not being pulled into the meter reading table - ive got no other fields in
the main form, could that be the problem, should i have the meterID in there
somewhere (that doesnt make sense though)

this is the row source SELECT [ElectricityMeter].[ElectricityMeterID],
[ElectricityMeter].[MeterNumber] FROM ElectricityMeter ORDER BY
[MeterNumber];

nothing else is set, no events etc

the subform is set up correctly - i checked, child and master are set to
ElectricityMeterID and thats the link field and it drops the readings into
the table nicely so it must be set up correctly - its just the meter number
from the main form thats not working

i've stumbled my way through waaaaay more complicated forms than this -
aaaarrrrggg!

my combo box works and the subtable works - checked all the things you
mentioned and everything is in the right spot, its just not picking up the
meter number in the meter reading table when you input a new reading, the
date shows, the readings show but the meter number spot is blank
