I have a sheet that in column B are times of 6:00 a.m. on down to 2:00 p.m. and in column c are times of 6:30 a.m. on down to 2:30 p.m. in cells F9 thru k9 are times in which a user will enter. How can i have these times the user enters look up in column B and C and if the time falls between the two times a worksheet change event will occur. so say cell B14 is 8:00 a.m. and cell C14 is 8:30 a.m. and cell G9 is 8:15 a.m., in cell G14 a worksheet change will occur.
