text() to screen, not print() to compiler

General
1

Can anyone look at this and see whats wrong, trying to get the print out to the screen not the compiler.
when I change the print to text, I dont see anything. Why ?

--Press "h" for hit, "s" for stay, 
--and "a" to play again. 
--It's in portrait mode

I’m not at my iPad to check this, but I notice that you’re concatenating the strings right in the text() statement. I don’t know if that’s it, but you might try concatenating them first and then putting them in the text() statement.

@kendog400 You’re not telling the text statement where on the screen to display. Anytime you have trouble with a statement, try looking at the built in reference to see how to use that statement. An easy way is to double tap on the word text and select reference from the popup.

@kendog400 The code you show above is what I wrote for you back in August using print statements. Here’s the original post.

Yes, dave1707, this was the code you orginally wrote.
If I can get this rolling, it would be a Major step foward.
Everything in the game works fine. I would like to get the cards on the screen and apply this knowledge to my own card games. Do you see anything wrong that I’m doing ? This Codea software is as only as good as the persons knowledge and ability to use it. Thanks in advance.

@kendog400 Here a version that uses text.

Do you want prompts displayed as messages to the screen? If so, try creating a class that holds an array of messages you want to show. Tween them one by one to the screen by drawing them with text. You should try to figure it out yourself before anyone gives you the code.

Thank you everyone for the help…
