SYMPTOMS
When you concatenate (join) several pieces of information together in a Microsoft Excel macro, the following error message may appear:

Run-time Error '13':

Type mismatch

 * You use the plus sign, instead of the ampersand (&), as the concatenation operator in a macro.

-and-
 * You concatenate a text string and a numeric value.



WORKAROUND
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. To work around this problem, use either of the following methods.

Method 1: Use the Ampersand Operator Instead of the Plus Sign
Sub Concatenate

Dim part1 ' Declare variable. Dim part2 ' Declare variable. part1 = "abc" part2 = 123 MsgBox part1 & part2

End Sub

Method 2: Assign the Numeric Variable to a String Value
Sub Concatenate

Dim part1 ' Declare variable. Dim part2 ' Declare variable. part1 = "abc" part2 = "123" MsgBox part1 + part2

End Sub



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.



MORE INFORMATION
Use the ampersand operator to connect or concatenate two or more values to produce one text value. Use the plus operator to perform addition on two or more numeric values. Although you can use the plus sign for concatenation, using the ampersand eliminates ambiguity.
