Creating functions that call to non existing ones

Hi.

I have some sql scripts. A couple of them use other functions that I have not created yet, so I get next message:

"Cannot find either column “dbo” or the user-defined function or aggregate “dbo.MyOtherFunction”, or the name is ambiguous"

Is there any way to create a function and sql server avoids to check if the function I use inside the script exists?

Thanks anyway!!
