Interesting my code works fine for me I don’t need to use .form![id]
though it doesn’t matter it did not work for him.

BWAHAHA

My fault I am so sorry and well-done to Tom van Stiphout FOR THE COPY
PASTE OF MY MISTAKE =P

[ID]=[Forms]![ frmSwitchboard]![subfrmswitchboard]![ID]

There is a space there you’ll see it if you look close

Try this

[ID]=[Forms]![frmSwitchboard]![subfrmswitchboard]![ID]
