Chapter Notes

3-D references

A 3-D reference is a pointer to a cell in the other worksheet [1]. In a 3-D reference, the worksheet name is separated from the cell reference by an exclamation mark.

 =SUM(‘First Worksheet:Last Worksheet’!RangeOfCells)

For example, in =SUM(‘Qtr1:Qtr4’!E3), Qtr1:Qtr4 are four worksheets named Qtr1, Qtr2, Qtr3, and Qtr4. E3 refers to a cell on each of those worksheets.

Tips & Tricks

3-D references

Don't type 3-D references - you can, but it's easy to make a mistake!  Start the formula then click on the worksheet and cell you want to reference! It's much easier [2].
