Dumb question: variables in the statusline

(Maybe this will be like last time, where I just had to send the question to the list before I could realize how idiotically wrong I was...)

I have a function which takes ... arguments, and when I try to call it from another function to set the statusline, I basically get:

E121: Undefined variable: a:1

E116: Invalid arguments for function FunctionFromWhichIAmTryingToGetAStatusline(a:1)

So the function getting the error is more or less:

function! SetUpTheStatusline(...)

  setlocal statusline=%!FunctionFromWhichIAmTryingToGetAStatusline(a:1)

endfunction

And that is just getting those two errors.

To be clear, I have verified that there is indeed a:1 in the SetUpTheStatusline() function. I can do (it seems) anything with it -- even use it in the call to FunctionFromWhichIAmTryingToGetAStatusline() -- except for using it in a function called in the statusline.

What am I doing wrong?
