How can I create an IF statement that will find duplicate entries in 10 Text Boxes within a User Form?

My UserForm has 10 TextBoxes into which the user can input an alphanumeric code with the format AB12-34

I would like to introduce an IF statement that runs when the OK button is clicked that compares each of the strings contained within the TextBoxes, and if there is a duplicate it will run some more code.

If the TextBoxes do not contain data then I do not want them to be considered duplicates.

Thanks in advance

First thing that's coming to my mind is putting all of the values in an array, sorting the array, then just testing for duplicates in the surrounding values.

So for example

a[0] = 1
a[1] = 3
a[2] = 1

You would sort the array so it would then be a[0] = 1, a[1] = 1, a[2] = 3. Then loop a test that checks if a[0] == a[0+1] or if a[1] == a[1+1].

Thanks for your response.
Unfortunately my knowledge is limited and I need you to spell it out to me...
I'm not sure how to compile this in VBA

Thanks for the pointer.
Because I didn't know how to "sort the array" I copied the data to a range of cells with code first, and then checked for duplicates there with an IF statement.
