Multi-bitrate live streaming?

Hi, does anybody know the syntax for the FMS URL -parameter when streaming multiple bitrate live streams with FMLE 3 to FMIS 3.5? E.g. when I select the FMLE-preset: Multiple Bitrate - 3 streams (1500Kbps), for the FMS URL Flash Media Encoder just tells me that:

"On replacing tags in stream name with their values, two or more streams have the same name. Please us %i tag in stream name to prevent this from happening"

So does anybody know the correct form for the FMS URL in this case, thanks!
