How to hide text in a Excel cell and display it when needed

Hi friends

I have doubt in excel.
I have a column called 'Status' and want to show the text either as 'Pending' or 'Completed' depending on the result received when two other columns (Total Fees $ Total Paid) gets added.
I have added the formula and applied to the entire column. The formula works.
But the text 'Pending' is showing in all the below cells even when there is no data in other cells.
I only want the text to be shown when something is entered in 'Total Fees' column.
Please tell me how to do that.

Thanks

John Thomas
