Adding form to nested if statements?

[phpnoobie9]

I have a bunch of if statements that I want to echo a form inside...how can I do it I seem to keep getting blanks.

if () {
if () {
}
  if () {
  }
if all the ifs are true echo the form here??
}
else {
echo 'error';
}

if () 
{
if () 
	{ 
	if () 
		{ 
		//echo form.
		}  	  
 	 }
}
else 
{
echo 'error';
}
