What I want to do now is to keep all the vector elements (only numbers) without the zeros!. How I can do that?

This works. Now I want to do the opposite let's say that I have one sequence for example check in image http://imageshack.us/photo/my-images/4/unleduso.png/ column A (this is a seq(1,113,4) and I want when I get the number 9 to say that this is the third number in the seq (1,113,4). everything about the seq(1,113,4) is known and I want when I get one of the number of the sequence to say which is its order. How I can do that?
