Hi
A couple of things to check first:
It is possible to import selection names from Excel but it would be much easier to have your selection names in a text file. The following two videos give an idea of how this would be done.

this trigger does not need the import process, it uses a condition to check if the selection's name is in the text file
back
price: back_price
amount: xx
all matching selections
once per market
conditions:
markets minutes before the off is less than 2.00
and selections name is in file ...path to .txt file
and selections back price is greater than 2.40
if you want to go Excel route it can be done, worth looking at the Excel Interface section of the help file
