I'm programming a 99 bottles of beer on the wall program and I have one error reading "Expected unqualified -id" on it... I can't figure out why it's there.

The reason it isn't working is because you have an if statement just sitting there in the global scope, it needs to be in a function somewhere.
It looks like it should be in your 'int2word' function, so change it to something like this.
1 2 3 4 5 6 7 8 9 10 11 12
string int2word(int num)
{
string ret;
if (!(num <= 19 && num > 0))
{
ret = tens(num/10) + "-" + ones(num%10);
return ret;
}
//Needs check for rest of numbers
}
The second problem is you can't follow an if statement directly with a !. You need to include another set of () if you want to check the variables inside of it (as added in the code above).
Also don't forget your teens function is meant to be returning a string, but it isn't returning anything right now.

Also on the code above the function names shouldn't have ; on them (which seem to have been added) and your teens function still needs to return a value.
