[Error] too few arguments to function

So I'm writing some code for a project and I'm stuck on the first part. This code is obviously unfinished, but I tried testing it just to see how it was coming along and I kept getting the [Error] too few arguments to function 'output_short_format'. As far as I can tell, I'm passing three arguments into the function which takes three arguments. I don't see the problem.
C:
#include <stdio.h>
#include <math.h>
void output_short_format (double, double, double);
int main () {
    int x, amount, int_rate, term, mon_int_rate;
    printf ("Welcome to Mortgage Calculator!\nPlease select from the options below.\n\n");
    printf ("For 'Short Format' press 1\n\nFor 'Amortized Schedule' press 2\n\nFor 'Monthly Early Payments' press 3\n\nFor 'Yearly Early Payments' press 4\n\n");
    printf ("Where would you like to go? ");
    scanf ("%d", &x);
    if (x=1) {
        system ("cls");
        printf ("---------------------------------\n");
        printf ("           LOAN TERMS\n");
        printf ("---------------------------------\n");
        amount = 150000;
        int_rate = 4;
        term = 15;
        printf ("Loan Amount: %15d\n", amount);
        printf ("Interest Rate: %12d%%\n", int_rate);
        printf ("Term: %16d years\n", term);
        printf ("---------------------------------\n\n");
        mon_int_rate = int_rate/1200;
        output_short_format (double amount, double mon_int_rate, double term);
    }
}
    void output_short_format (double loan_amount, double interest_rate, double term_years) {
    int months, p;
    months = term_years*12;
    p = (loan_amount*interest_rate*pow (1+interest_rate, months))/(pow (1+interest_rate, months)-1);
    printf ("Monthly payment is: %12d", p);
    printf ("Total interest is: %12d", interest_rate); \\ignore
    printf ("Total amount paid is: %12d", term_years); \\ignore
}

Never mind, I figured it out.

Just in case, the problem is when you called your function -- don't declare the parameter types when you call a function. The declarations of the parameters go in the function prototype (which you have in the third line) and in the function definition.

Also, I changed your opening code tags slightly, using [code=c] instead of just [code].
