function for greatest object in list less than or equal to a value

Jacque,


My gadget adds the index in a parameter to the function. if it already exists in the list, the addition is superfluous, but harmless.

I thought of that too, but it fails if tIndex isn't in
the list. The 
example list was: "1,3,4,7,9" and the target limit was 5.

I
couldn't see a way that avoids looping through all the values.
