This is a great explanation and makes sense. Thank you. I implemented the idea in my app; however, the text value in the somechild2 is not populating. What do I need to set "text" as in the second child? I tried setting it to "", I tried leaving it out, but it won't set when I run the app.
Also, if I want to set a variable in the parentDocument based on this text value, can I call a setVariable function from the child? The script in child1 would like to access a function in the parentDocument. Can I call it this way? parentDocument.setVariable() Thanks --- In [email protected], Gordon Smith <[EMAIL PROTECTED]> wrote: > Certainly.
