How to turn VBA Code to auto calculate sums in workbook?

[jerehall14]

I copied and pasted a well used VBA code for the first time today to sum colored cells in a given range. The issue I am running into is that it wont auto calculate the sum. It only calculates if you click the cell with the formula and press enter manually. Again, I am not familiar with VBA and so I'm hoping there is a simple solution I can follow! Thanks
