Heya, Honey99.

Thanks for using CODE tags! Did you know that you can specify a language for your CODE tags to make your source code easier to read (and therefore make our Experts more likely to post solutions)?

You will still need to use [/CODE] to close your code blocks, regardless of the language, but you can the use one of these tags to open your code block:

[CODE=html]
[CODE=javascript]
[CODE=php]

and so on.

Thanks!
