attachURL - div id not found

I attach an URL to cell(“b”) of an accordion. This work fine - URL is attached.

HTML is very simple:

some text here for test

If I try to access “gridarea3” in the “onContentLoaded” of cell(“b”) I´ll get back

document.getElementById(“gridarea3”) is null

grid_paging.html (461 Bytes)

Sorry, miss to add my HTML as attachement
