I'm getting the error when trying to link a form and a subform with ID beeing type BIGINT
"One of your parameter is invalid"
Form is done using record like :
ID : bigint
Value A : int
Subform is done using record like :
ID : bigint
Value B : int
The ID type cannot be change to INT as they come from SQL linked table created by an external software
Linked Master Field : ID
Linked Child Field : ID
As Gustav proposed :
Creating a value ID2: CLng(ID)
and use this value to link the form solved the issue
