# ExcelMultiple If True Values - IF Function Excel

#### hue

Not an expert so I need allot of help. In a production schedule I have various models to make with X number of units per model in a day. Using VLOOKUP I have a time value (production time) column for each model multiplied by its number of units, so I know the time it takes to produce each individual model in a day. I now need to include a PST (Production Standard Time) column for each model so workers can know at what time they should finish each of the models in the daily schedule. During our work hours (7:00am - 5:06pm) I have 3 lunch/rest breaks one @ 9:20 am(lasts 19min), 12:30 pm(lasts 29min) and 3:00 pm(lasts 9min) so I need to add to the PST that specific lunch/rest time if a model is finished during any of the lunch/rest periods, so I’ll assure the PST is accurate. How can achieve this using one single formula, considering the 3 criteria?

Criteria #1: IF((A1+B1)>=timevalue("9:20 am") but <=timevalue("12:30 pm"), (A1+B1)+time(0,19,0), (A1+B1))
Criteria #2: IF((A1+B1)>=timevalue("12:30 pm") but <=timevalue("3:00 pm"), (A1+B1)+time(0,29,0), (A1+B1))
Criteria #3: IF((A1+B1)>=timevalue("3:00 pm"), (A1+B1)+time(0,9,0), (A1+B1))

Since the values will be adding up as the day goes, it can occur, that the value (A1+B1) falls directly into the second criteria (eg. 1:37 pm), I need then for it to add the 29 minutes plus the 19 of the first criteria, and so on and so forth. Thanks so much in advance.
