please edit your post, select the code part and press the </> icon in the tool bar to mark it as code. It’s barely readable as it stands. (also make sure you indented the code in the IDE before copying, that’s done by pressing ctrlT on a PC or cmdT on a Mac)

Once this is done explain what is the error…

[agreyg]

i am a new guy here so i don't know to edit code will u tell me

[J-M-L]

Go read the stickies pinned at the top of the forum. You’ll see the forum’s rule. That’s where you usually start when you want to join a group…

Please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

Hello and good morning
did you ask for in the WWW to find:
