How can I enter a formula in a cell, but have the cell display something completely different.

My particular formula happens to be:
"=(B5*D19*B7)-((B11*D19*B7)+B15+B16)".
However, I want the cell to display the word "Customer" and nothing else.

I just need the formula in that cell in order to for a data table to reference it.

Thanks,
Bryan
