    Hi,

    Whenever I install the plugin, I get a warning that there are header errors upon activation, then I get server errors when I try to embed the shortcode in your tutorials into a post.

    The initial error I get on two different WordPress sites is:
    —
    The plugin generated 3 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
    —

    Please help.

    Cheers,

    Sam

    Fixed the activation bugs and pushed a new version of the plugin – it was a simple whitespace problem that I should have picked up on.

    You say you are getting server errors on the examples. Can you give me some more details? Are theyL
    * Vixo server errors
    * WordPress server errors
    * page not found notices
    * etc, etc

    Thank-you for the quick fix – excellent!

    The other error message I was getting was a WordPress header feed error. But this has been fixed since you sorted out the whitespace in the plugin. Thanks.

    One more question – I would like to create a form that calculates a user’s input, and then shows that in a chart right underneath the result. The form is like the one linked below. Can you let me know if this is possible within your WordPress plugin?

    Absolutely

    What you want is a form of calculator. There is a calculator HOWTO on the plugin site:

    When you build the calculator you can add a graph to it (just like in a spreadsheet).

    Have a go with the HOWTO and if you hit any problems get back to me.
