Dear Sir
We have columns in an excel spreadsheet whereby some cells have numbers while also empty cells.
We want the formula to trace back to the last time when the numbers in a column were at most one cell apart.
There are two possible scenarios for this:
1) there are numbers in consecutive cells; or
2) the numbers are exactly 1 cell apart
Please refer to the enclosed excel spreadsheet for illustration.
Can you help us with suggesting a formula ?
Thank you very much!
