Hi. I am using excel 2007 and I need help with the following if anyone would be kind enough. I have a dynamic array that consists of stream of 1's and 0's. I want to be able to find the largest sequence of 1's and the smallest sequence of 1's. So at a point in time the array mite be 111110001101111000 and I want to be able to dertermine the longest contiguous sequence of 1's. But as I say the array is dynamic and so I need to do that after each input. All and any help appreciated. Thanks.
