link commandbuttons on userform and sheet

[cfinch100]

hi
i have now sorted most of this apart from linking commandbuttons together ,i have cmd1 on frmret,cmd2 on sheet3,cmd3 and cmd4 on frmret,these need to
be done in this order,cmd1 saves to sheet3,then cmd2 combines together,cmd3 then posts to sheet4,cmd4 then deletes,have done the rounds on the forums
and can not figure this one out at all,does any one know the best way to do this please,ideas,pointers anything at all would be gratefully received
cheers colin
