I am a beginner in VBA programming and I have a worry in the execution of a macro from a user form.
The easiest way would be to put your macros in a public module by specifying the sheet on which you want to intervene.
Alternatively, declare your macro by Target.
Public Sub Test ()
In the Userform:
Private Sub UserForm_Click () Feuil1.Test 'or Sheets ("Sheet1"). End Sub Test
