yes that's correct...but it depends on your data as to whether it will be blank or find a value...i assumeed one space between each ite,.
if there are TWO spaces between each element in your data, it would probably find every other item..3 spaces between each, then it would find nothing but the first item in our example.
you'll need to look at the actual data in f1: what does the column actually contain?
