problem assigning macro to button

[kristie]

I have currently got three buttons in operation on my spreadshett-each with their macro working perfectly. however i am having difficulty assigning a macro to a new button it keeps giving me an error message: Formula is too complex to be assigned to object.
if anyone has any words of advice for me that would be great!
thank you in advance.
