Using macro to get the value of Editable Text Region

I need to configure one repeater based on the value of text field in the same page. I used macro to read the content using. I use the following macro to get the value

{% CurrentDocument.DocumentContent["editabletext"] #%}

Its returns the value in page which was enter but not return the value in Child page which need to be inherit from the parent content. Is there any other way to read the content on child page also.
