Auto close 'overwrite existing data' box

I am very new to excel's macros and vba coding...

I've made my first macro to run 16 regressions, but 16 times I get the warning box for overwriting existing data, so I have to click OK button 16 times in a row and it annoys me.

Application.DisplayAlerts = False
I tried this solution, put it everywhere in the script but it doesn't help.

Any ideas?

Thanks!
