Matching values from 2 columns and returning the value in 3rd column

I have been trying to work out this formula for days without any luck. Please see attached file for a better udnerstanding of what I am trying to achieve.

I need to lookup the value in column a and match this to a value in column b to return the value that appears in column e. For example, i want to know how much time Tim Smith has spent on training creation, then i would need to check a11 and b11 and the value i want the formula to return is e11.

Please can someone assist with the formula I need to be using?

Thanks in advance!
