Thanks Max!! Just goes to show us that Excel is an amazing tool with lots of
flexibility that takes time to learn! I'm glad we have this resource to ask
questions and share knowledge!

The control is in the book's calc mode. You can set the calc mode to
"Manual", via ToolsOptionsCalculations tab. Then press F9 only whenever
re-calc is required (after you complete each batch of data entry, etc).

I have a large array and the formulas take about 30 seconds to calculate
everytime I enter any new data. Is there a way to suppress the calculations
until I've entered all my data each time I make changes, so the calculations
are done only once when I'm finished entering new data? Perhaps using on IF
condition in the array formula and satisfying the IF condition by unchecking
a box when I'm ready for the calculations.
