CountIf statement driven by spesific date and text criteria

Hello,

Employee Work Code Report

I need to summarize every occurrence in column C
within each of the same dates in column D (1/1-1/31)
and based on a specific code.
Also this logic is driven by employee last name

Example : 100 rows of raw data spanning the range of 1/1-1/31, I need to be able to say:
"on 1/2, Smith entered 'Code : A' [this] many times. "
"On 1/3, Smith entered 'Code : A' this many time"

While your at it, mind picking up dinner too? :)

Any info will be very much appreciated.
