passing tv's from children pages into ditto call

Hi can anybody help, I want to make a ditto call that takes template variables from the children pages

If I am understand you correctly, just use placeholders with the TV name, [+tvname+] in the chunk tpl for the Ditto items.

thank you, documentation isn’t great on this end of Modx. How do I sort by the menu index?

&orderBy=`menuindex ASC` or &orderBy=`menuindex DESC`
Parameter documentation is on the Ditto site at http://ditto.modxcms.com/files/snippet-ditto-php.html. A lot of this is also in the comments in snippet code itself.
For more, see wiki articles on Ditto and guide to Ditto with examples on Pogwatch
Note also there’s a dedicated Ditto sub-forum.
