Linked list not Printing?

Okay this is making me sweat. I have a program that is compiling, but I am not receiving my desired output when I execute it on gcc, instead the output is Error. I am pretty sure my code and call for Print is at least correct. I can't find any error in my program that would mess up the output. This is my code

#include <stdio.h>
#include <stdlib.h>
typedef struct node{
    int data;
    struct node *next;
}node;
node *Inserttail(node *head, int x){
    node *temp = (node*)malloc(sizeof(node));
    temp->data = x;
    temp->next = NULL;
    node *temp1 = head;
    if(head==NULL)
        return temp;
    else if(head->next ==NULL){
        head ->next = temp;
        return head;
    }
    while(head->next != NULL)
        head = head->next;
    head->next = temp;
    return temp1;
}
void Print(node *head){
    if(head == NULL)
        printf("Error");
    while(head != NULL){
        printf("%d ", head->data);
        head = head->next;
    }
    printf("\n");
}
node *Deletemultiples(node *head, int k){
    node *temp = head, *old = temp;
    if(head == NULL)
        return NULL;
    if(head->data == 1)
        head= head->next;
    while(temp!=NULL){
        if(temp->data %k ==0 && temp->data != k)
            old->next = temp->next;
        old=temp;
        temp= temp->next;
    }
    return head;
}
void Freelist(node *head){
    node *temp = head;
    while(head != NULL){
        head = head -> next;
        free(temp);
        temp = head;
    }
}
int main(){
    node *head = NULL;
    int i;
    for(i=1; i<=1000; i++)
        head = Inserttail(head, i);
    for(i=2; i<=32; i++){
        head = Deletemultiples(head, i);
    }
    Print(head);
    Freelist(head);
    return 0;
}

Because of the if statement before the printf, I believe there is something wrong with head, I just can't find the issue.Any thoughts?

your code is correct. i run it under ubuntu 16.04 LTS with gcc 5.4.0 and all things are OK.
