Working on a PC running XP Pro, using InDesign CS2, I am doing a directory of information about trees. I am working on a master page which has a header, as well as a footer that has a page number on it (left side pages numbered on the left, right side numbered on the right)and two columns. Each 3-line entry takes up the column width, by 1/2" of depth, which includes a bit of extra space between entries. I'm estimating that I will have 16 pages.
Each kind of information for each entry is designated in different character styles, for example:
Line 1: Common Name is Bold, 12 point, genus and species is a different typeface and medium italic, 10 point all in PMS color.
Line 2: new typeface with 5 tabs, all black
Line 3: 2 tabbed entries of information in same typeface as line 2, then first and last name of owner tabbed to the far right and in italic.
Seems to me that I should be able to import my information from Excel into pre-formatted fields, right? And that it should just merge beautifully down two columns per page til it gets to the end, right? Yeah, that's what I thought, but I am truly stumped. It seems like I don't have enough places in the data merge pallet to tell InDesign all this stuff. I need help from a guru, please!

Thanks,
Peggy
