recursion script problem

Hi Guys,,

I tried to create a recursive function in unix.
The following is the code.

Code:

#/bin/sh

function(){
n=$1;

if [ $n -eq "0" ]; then

out=1;
echo "inside if for 0";

else
out = `$n * function "$n-1"`;
echo "inside if for $n-1;
fi

echo out;
}

input=$1;
echo "$input";
function "$input";

But it is giving an error.This is the error "function()recurs.ksh[3]: 0403-057 Syntax error at line 3 : `(' is not expected."

Can you please help me in debugging it.

Thanks for ur help in advance,,
Regards,
Magesh.
