pause one movie symbol while another plays, then resume the first based on a counter

I have a counter running on my main flash document. I have 2 movie symbols sitting on the main document as well. I want the 'facts' symbol to play
constantly (it's a long loop) unless the counter gets to a certain value. Once it hits that value, I want the 'facts' movie symbol to pause, the second movie 'special' to play and the once it finishes, resume the 'facts' movie where it left off. Actionscript 2. Any ideas? Here's my counter code:

var textValue:Number = 0; // starting value
var addValue:Number = 61; // how much it should add for every 30th second
var pagestring:String = new String();


function counter()
{
textValue += addValue;
if (length(textValue) > 3)
{
pagestring = String(textValue).substr (length(textValue)-3,3);
for (digit = length (textValue) - 6; digit >= 0; digit = digit - 3)
{
pagestring = String(textValue).substr (digit,3) + "," + pagestring;
}
if (digit > -3)
{
pagestring = String(textValue).substr (0,digit+3) +","+ pagestring;
}
} else
{
pagestring = String(textValue);
}
pros_pages.text = pagestring;
}

}

setInterval(counter, 1000);
