millerdr,
Sure smells like the channel references are in Group and channel number mode.
I prefer using group name and channel name mode. That way the group names and channel names have to match for the channel to be put in report.
Anyway the attached word doc shows how to set it to name mode from index mode.
Also you can look at the report to see how it is referencing the channel by selecting the report object and then right click then select display.

ps. you can also see what the tdm file index numbers are for each group and channel by looking in the data portal properties.
