Button who activates a macro

Hello
First i want to tell me how i write the code here, because I saw that you put into some kind of window.
The I have a module which it's a macro who is actually an amount of macros.
I want to put a button somewhere in sheet 1 or sheet 2 that activate this macro.
The macro looks like this:

Sub Main()
Call muta
Call Spatii
Call Precuratat
Call Sortat
Call Curatat
Call OneCell
Call OneCell2
End Sub
If there are problems I'll return with other explanations
Thank you!

Doesn't work. It appears an error, something like the sub procedure is not defined.
When i put one macro works just fine, but when I put another one under the first one, appears this error.
Another problem. My button is in sheet 2 and the text is in sheet 1.
This is my button and "muta" and Spatii" are the 2 macros:

Private Sub CommandButton1_Click()
Worksheets("sheet1").Activate
muta
Spatii
End Sub

I figure it out just before I saw your post
I delete Private from one of the macros and now it works perfect
Thank you for everything
