Please can somebody help me.
I have a workbook that contains 2 sheets.
In sheet1 and column A there is a date and time and in sheet2 columns A and B a from and to date and time.
There are a number of rows in each sheet.
I would like a formula that searches sheet2 and puts a 1 in sheet1 column B where the value finds a match between the to and from date and time in sheet2 for every match it finds.
Thank you.
