[RESOLVED] Problem using a timer to change div styles

[chris1990]

I've created a page to show a 'please wait' box then using a timer to hide the 'please wait' box and show other div elements.

function StartTheTimer(){
    if (secs==0)
    {
        StopTheClock()
        // when finished show quote and continue
		document.getElementById("form-pagebreak-back_14").style="display:block;"
		document.getElementById("form-pagebreak-next_14").style="display:block;"

		document.getElementById("id_15").style="display:block;"
		document.getElementById("id_168").style="display:block;"
		document.getElementById("id_178").style="display:block;"
		document.getElementById("id_18").style="display:block;"
		document.getElementById("id_4").style="display:block;"
		document.getElementById("cid_4").style="display:block;"
    }
    else
    {
        self.status = secs
        secs = secs - 1
        timerRunning = true
        timerID = self.setTimeout("StartTheTimer()", delay)
    }

I use the Free Javascript Editor and when i run the code it stops at this line and says 'not implemented'.

document.getElementById("form-pagebreak-back_14").style="display:block;"

Thanks in advance, Chris1990.
