< Run-time error'380' Could not set the RowSource property. Invalid property value> on Mac

Hi,

I generated a VBA userform using 365. The code works fine on a PC. However, when I try to share the document with Mac users, I get a run-time error <Run-time error'380' Could not set the RowSource property. Invalid property value.> When I access the document on a Mac, the debugging error comes in the:

Sub Show_For ()
SampleSubmissionForm.()
End Sub

Can someone please help? Thanks in advanced
