Problem: Return Value of Function

ok... the issue here is the visibility of the variables.

in

 Function strFunctionTest(strTest)
         strTest = "New"
         strFunctionTest = strTest    
     End Function

you are only setting strFunctionTest to strTest, but in the return of it, you are not using it. Try something more like this

     Response.Write("This is the value of strTest: " & strTest & "<br>")    
     Response.Write("This is the value of strArguement: " & strArguement & "<br>")
    strTest = strFunctionTest(strTest);
    Response.Write("This is the returned value of the function when strArguement is passed: " & strTest  & "<br>")

seems odd what you are trying doing, but I assume you are only testing.

You could also change your function to do this


  Function strFunctionTest(strTest)
         strFunctionTest = "New"
     End Function

But then, I'm not sure why you would be passing in a variable. Any ways, what I did above in the Response.Write should be what you are looking for.

change your function to:

Function strFunctionTest(strTest)
    strFunctionTest = "New"
End Function

My apologies. The code was supposed to be:

<%@ Language = VBScript %>
<%  Option Explicit %>
<%
      Function strFunctionTest(strTest)
            strTest = "New"
            strFunctionTest = strTest      
      End Function
      
      Dim strTest, strArguement
      strTest = "Different"
      strArguement = "Original"
      
      Response.Write("This is the value of strTest: " & strTest & "<br>")      
      Response.Write("This is the value of strArguement: " & strArguement & "<br>")
      Response.Write("This is the returned value of the function when strArguement is passed: " & strFunctionTest(strArguement)  & "<br>")
      Response.Write("Why did strTest change? It is now: " & strTest)      
%>

Unfortunately, this code is working the way it’s supposed to. I made the above program to simplify the problem I am having with a more complex program. Here’s the basic idea of what’s going wrong with my code:

strTest = “Different”
strArguement = “Original”

strArguement = strFunctionTest(strTest)      ‘ Returns “New” and assigns to strArgument

The problem is with strTest. It ends up having the same value as strArguement after the function call, which is “New.” I will examine my code closer and try to post a clearer description of my problem.

When a variable that exist as global is changed in a function (which should be local to the function), it should not affect the global variable's value, right?

I hope the following code makes more sense:

<%@ Language = VBScript %>
<%  Option Explicit %>
<%
      Function strFunctionTest(strTest)
            strTest = "This variable should be local to this function!"
            strFunctionTest = "New"
      End Function
      
      Dim strTest, strArguement
      strTest = "Different from strArguement"
      strArguement = "Original"

      Response.Write("strTest is currently: " & strTest & "<br>")
      Response.Write("strArguement is currently: " & strArguement & "<br>")
      strArguement = strFunctionTest(strTest)
      Response.Write("After function call that returns 'New' and assigns it to strArguement, strArguement is now: " & strArguement & "<br>")
      Response.Write("strTest is now: " & strTest)      ' strTest should NOT be a changed value at this point      
%>
