Ok, when I try to put a literal string into my fnction I get:

Missing argument 2 for telephone_check() in blah
Missing argument 3 for telephone_check() in blah
Missing argument 4 for telephone_check() in blah

So obviously I'm getting it wrong. It isn't recognising the strings I am
puttin I at positions 2,3,and 4 as corresponding to the variable positions
in my function as $empty, $wrong, $correct.

The code I'm using is...

$telephone_check = telephone_check($telephone, "Pease enter number", "Duff
number", "Looks good");

The function is:

function telephone_check($var, $empty, $wrong, $correct)
{
//check if variable exists
if (!$var)
{
return $empty;
}
elseif (!eregi("^[0-9\ \(\)\+\-]{10,}$",$var))
{
return $wrong;
}
else
{
return $correct;
}
}

So can anyone show me what I am doing wrong here. Is there some special
syntax I need to use when declaring the variable that says "I'll be putting
a string in this position?
