I hope I can explain myself. I have a spreadsheet that lists room numbers in a hospital. The room numbers in this facility have corresponding unit numbers (i.e. rooms 103 to 133 are considered Unit A1, rooms 203 to 233 are considered Unit A2 and rooms 303 to 333 are Unit A3). My spreadsheet is set up with the Unit name in Column F and the Room number in Column G. The Unit number is blank, as my download from another program will list room number only and not Unit number. I would like the formula to reference the room number in column G and return the corresponding Unit Number in Column F. My problem is as follows, the Room Nmbers have letters next to them (i.e. Room 108D, 328P or 215A). Is there a way to have the formula return the absolute value of A1 for rooms 103-133 even if there is a letter next to some of the room numbers? Any help is greatly appreciated. Thanks.
