Actionscript used to load dynamically created swf files

Hi there

Trying to load dynamically created swf files into flash using the following action script. The swf are created from jpegs using php to convert to swf. The movies are named in series fire1, fire2 etc...
What syntax is necessary to automatically call the next swf into flash, meaning fire2.swf, fire3.swf etc.....?? thanx

for (i=1; i<4; i++)
{

loadMovieNum("fire1.swf", 1, "POST");

}

Try this:

for (i=1; i<4; i++) {

nexturl = "fire"+ i + ".swf";

loadMovieNum(nexturl, 1, "POST");

}
