Pass Variable Form Name to another form in Access

I have three forms.
A, B, C On which all the field names are standard
I have a second form (NOINE) which I would only like to code once.
When A is open and I push a button I want NOINE to open and reference fields on form A
When B is open and I push a button I want NOINE to open and reference fields on form B

How do I pass the form name as a variable so in my text fields on Form Noine I am effectively referencing it like this

[Forms]![FormA]![Standard Field Name Across all forms A, B, C]

[Forms]![Whatever Variable Name I Pass from the button]![Standard Field Name Across all forms A, B, C]
