Easy Noob question: using tv check box

Hi there,

I've googled around and can't find an obvious answer so I'm hoping someone can help.
I've created a check box tv and I want to output a certain piece of html within a chunk when it's checked.

How is this done?

Thanks in advance!

Which version of MODX you are using?

I guess with Input and Output Modifiers? http://rtfm.modx.com/display/revolution20/Input+and+Output+Filters+%28Output+Modifiers%29

Example:

Thanks for that,

It doesn't seem to work though.
I'm using Rev 2.1.

Basically I've created a tv with a single checkbox that I can check to make a certain block a html appear on a page if I want it.

I can't find any info on how to actually use checkbox tv's once you've created them.

Any help?

OK, I've worked it out.

What you have to do is:
1. Create a chunk containing the html you want to output.
2. Create a tv, input type = checkbox
3. For the tv Input Option Values put yes==[[$chunkName]] (where 'yes' is what you want written next to the checkbox.
4. Now all you have to do is call the tv wherever you want it: [[*tvName]]

If the checkbox is checked, it will output the chunk, otherwise nothing.
