Passing on arguments within functions

Hello there,
I have a question concerning passing variables from one function to the other, when executing a several functions, which build on each other.
For example
function [a, r, c] = func01 (s,t,y)
....
function [u,v,w] = func02 (a,b,d)
for 'a' i always get "Input argument is undefined" (although it seems to be in the workspace). I just can't figure out how to make it work. :( It's basic, I know, but still. Can anyone please tell me how to pass on arguments from one function to the other? Thanks!

How are you calling func02? And, as Oleg asks, what kind of function is func02 -- separate/regular function, subfunction of func01, nested function...?

As mentioned in the comments, it's not good enough for the variables to be in the workspace, if func02 is being called from inside func01. You have to pass the variable to func01, which can then pass it to func02.
If func02 is not being called from inside func01, it's not clear what the issue is. Are you able to post a snippet of code that exhibits the error?
