Selecting Item in Tree by Text

Hello all, thanks in advance for the assistance!

I am trying to write a script for SAP that I call from Excel, and I know from working with this for a few days now that finding the right syntax for things is not easy. Currently, I am working with transaction IH01 and have a tree (? I hope this is the right word for it) pulled up. Ideally, a user in Excel would type in or select something in English like "Bundler" and the item in the SAP tree with text "Bundler" would be selected. When I try to record a macro to find out what this item is called in SAP scripting, I get something like:

session.findById("wnd[0]/usr/cntlTREE_CONTAINER/shellcont/shell").selectItem "         24","1"

Does anybody know an alternative syntax so I do not have to manually build a database of these and use a lookup table in Excel? I'd ideally like to make this program reapplicable to different sets of "trees" and not have to go through the 300 entries in this tree and write down the  "         24","1" for each one!

Thanks!

Alex
