Finding columns count of a range

Below is some Excel VBA code that is supposed to print the column count of the range that is specified in the string. I am getting an error in the `Debug.Print` section. What am I doing wrong? ``` Dim val1a As String val1a = "A1:D1" Dim Rng1 As Range Debug.Print Rng1(var1a).Columns.Count ' error here ```
