Simplify Long Process Function

First ever post!

Hello. I am working on a project that has become rather large and I cant contine splitting processes.

Here is a chunk of code. Is there any way I can simplify it to save on space?

If UserForm1.ComboBox1 = "Haiti" Then
        If UserForm1.ComboBox2 = "Port-au-Prince" Then
        If UserForm1.ComboBox3 = "Terrorism" Then
            TextBox1.Text = Worksheets("xxxx").Range("B64")
            TextBox2.Text = Worksheets("xxxx").Range("J64")
            TextBox3.Text = Worksheets("xxxx").Range("K64")
            TextBox4.Text = Worksheets("xxxx").Range("L64")
            TextBox5.Text = Worksheets("xxxx").Range("M64")
            TextBox6.Text = Worksheets("xxxx").Range("N64")
            TextBox7.Text = Worksheets("xxxx").Range("O64")
            TextBox8.Text = Worksheets("xxxx").Range("P64")
            TextBox9.Text = Worksheets("xxxx").Range("Q64")
            TextBox10.Text = Worksheets("xxxx").Range("I64")
            TextBox11.Text = "Port-au-Prince, Haiti"
        End If
        End If
        End If
