Help with Chapter 4 Try it Out

RogueAkula · December 15th, 2013, 09:43 PM

I need a little help with the Try It Out for Chapter 4, specifically the Using the Wizard to Create Easy-to-Use-Forms. When I run the code in my browser (Chrome) it shows the language but not the name. I have looked at the code a hundred times now, but cant figure out what is wrong. I have posted the code and the behind code. Thanks in advance for your help.

I downloaded the code for the book and ran it and it worked fine. I did a line by line review and it looks like everything matched. Getting pretty frustrated.

Take a look at this:

Code:

Result.Text = "Your name is " & YourName.Text
Result.Text = "<br /> Your favorite language is " & FavoriteLanguage.SelectedValue

You're missing an & symbol on the second line, overwriting rather than appending to, the first line that sets the name:

Code:

Result.Text = "Your name is " & YourName.Text
Result.Text &= "<br /> Your favorite language is " & FavoriteLanguage.SelectedValue

Hope this helps,
