erlang - Calling a function from an .ERL to .YAWS file

Question

I am very new to YAWS and ERLANG and would like to call a function from a different .erl file to the YAWS page.

i.e. I have a page called webpage.yaws and have another file called utilities.erl and would like to call a function from utilities.erl in webpage.yaws

Any ideas?

Thanks
