Help: Macro works...But not on pressing button

Dear forum familie, (SOLVED, Thanks)

I'm working on a excel project and i'm a bit stuck.

I made a VBA script works fine if i call the macro from within the visual basic UI. But when i assign a button on that same macro it gives me a 400 error or it runs a part of it.

One button works fine tho, but why the errors on other buttons?

Anyone ever had such problem?


Hope you guys can help,

Mark

Below coding (not that it's necessary it works, only the buttons are doing weird...)

Sub Protocol_print(Optional PrPr As String)


Dim rng As Range, cell As Range

Application.StatusBar = "Protocollen wordt klaargemaakt..."
