Need a Formula to Identify a Value 3 or more times

[dsy12345]

Hello Excel Wizards. I need your help desperately. I need an excel formula or function that will identify part numbers in cells a2-A2335 that are listed in that column more than 3 times. In other words if I had the following numbers:

10
12
10
13
10

I need a function that will say, hey this part numbers are listed 3 times or more. Can someone help me with this function. I'm lost.

I posted another question earlier, can you look at that one and let me know your thoughts.

I found the error, thank you so much.
