Member function not found in BrightScript Component or interface.

I have made the homescreen using the posterscreen sample

Function Main() as void

menuFunctions = [ShowBonanzaMenu, ShowMovieMenu]

initTheme()

port=CreateObject("roMessagePort")

screen = CreateObject("roPosterScreen")

screen.SetMessagePort(port)

screen.SetListStyle("arced-landscape")

contentList = InitContentList()

screen.SetContent(contentList)

screen.Show()

while (true)

msg = wait(0, port)

if (type(msg) = "roPosterScreenEvent")

menuFunctions[msg.GetIndex()]()

endif

endif

end while

End Function

The main problem is that I keep getting this error
Member function not found in BrightScript Component or interface. (runtime error

 &hf4) in pkg:/source/Main.brs(22)
 Now this code worked before and I don't know why it wont now

Re: Member function not found in BrightScript Component or interface.

I'm going to guess and say that

 if (type(msg) = "roPosterScreenEvent")

 is causing it. Should be no parentheses around "type" or at the end.
same here. 
if (msg.isListItemSelected())

Extra parenthesis are fine, won't cause error. I don't see how the 1st line can cause the problem, so it must be the 2nd one.

And one more thing: something's wrong with the way Blackhawk posts code because there are is 1 extra empty line after every line of code, so we have to try and guess what was the line#.

You could try to change some of the above.
    theme.OverhangSliceHD = "pkg:/images/Overhang_Slice_HD.png"
    theme.OverhangPrimaryLogoSD = "pkg:/images/Logo_Overhang_SD43.png"
    theme.OverhangPrimaryLogoOffsetSD_X = "72"
    theme.OverhangPrimaryLogoOffsetSD_Y = "25"
    theme.OverhangPrimaryLogoHD = "pkg:/images/Logo_Overhang_HD.png"
    theme.OverhangPrimaryLogoOffsetHD_X = "123"
    theme.OverhangPrimaryLogoOffsetHD_Y = "48"

Count the actual code lines aka skip comments and white spaces then stop at 22. 🙂

I think if you are taking the time to answer, you shouldn't have to count. It's courtesy. 🙂

Oh yeah. I am totally going to do that! </sarcasm>
A bit more serious - i have done that - but really people, this forum is staffed by volunteers only (unfortunately) - so if you want help, make it easy on the helpers

As a minimum, at least post the actual, complete debugger output from the time of the crash, including the "list" command output, which will list the current file, including line numbers.

I was replying to you since your statement hinted it would be guesswork to find the line while you can eliminate the guesswork by logic. Granted, I agree that topic author could have been more helpful with his/her post.
