Formula Help. Sum of Cells if Certain Criteria is Met

Hellow everyone. Sorry if this has been answered already but I cannot find it. I am trying to create a formula that will search for employee numbers and add their sales value and spent values and report it on a seperate sheet which will contain a summary of all employees. So the formula would find all references to employee 1234 add their sales and spent columns and report "1234 Sales=1,500 and Spent=700.00". Thanks for your help.

Use Sumif

if your Summary sheet contains, employees down the left side, starting at A2, and you have 2 column headers starting at B1 labeled Sales and Spent, then formula would be:

=SUMIF('Sheet1'!$C:$C,$A2,'Sheet1'!D)

copied down and to next column.

Alternatively, you can use a Pivot Table, then drag Employee to Row label area, and Sales and Spent both get dragged to the Summation Area. This will autopopulate the unique employees and the respective sums.
