Hello, I am having to figure out a particularly painful excel formula. What i need is a formula that will count the number of times an issue label in text shows up, but it has to match a certain time.

we can get the excel sheet to round the time to the nearest thirty minutes, so if a call comes in at 3:12pm it rounds it to 3pm. We label the calls that come in with a issue description also like "dvr issue." So i need a formula that will allow me to count the number of instances where if it says 3pm AND dvr issue it will only count it and give me a total in a specified cell. Is that possible?
