Passing variables into AWK

I'm trying to use awk to write new entries to a hosts file if they don't exist. I need to do so depending on the type of system I have. Below is what I have, but it isn't working.

Code:

awk -v myip1=$IP1 myip2=$IP2 myhost1=$HOST1 myhost2=$HOST2'   BEGIN { mqhost1=0; mqhost2=0; stap1=0; stap2=0; }

    /mqhost1/   { mqhost1=1; }
     /mqhost2/    { mqhost2=1; }
       /myip1/    { stap1=1;   }
    /myip2/    { stap2=1;   }
                    { print $0; }
        END     { 
                  if (mqhost1 == 0)
                      printf("myip1          mqhost1.test.com       mqhost1      \n");
                  if (mqhost2 == 0)
                                      printf("myip2          mqhost2.test.com       mqhost2      \n");
                  if (stap1 == 0)
                      printf("$IP1          $HOST1.test.com   $HOST1  \n");
                  if (stap2 == 0)
                                      printf("$IP2          $HOST2.test.com   $HOST2  \n");

                  }' /client_root/etc/hosts > /home/me/hosts

krb5_get_krb_changepw_hst

KRB5_GET_KRBHST(3)					   BSD Library Functions Manual 					KRB5_GET_KRBHST(3)

NAME

     krb5_get_krbhst, krb5_get_krb_admin_hst, krb5_get_krb_changepw_hst, krb5_get_krb524hst, krb5_free_krbhst -- lookup Kerberos KDC hosts

LIBRARY

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

     #include <krb5.h>

     krb5_error_code
     krb5_get_krbhst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_get_krb_admin_hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_get_krb_changepw_hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_get_krb524hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_free_krbhst(krb5_context context, char **hostlist);

DESCRIPTION

     These functions implement the old API to get a list of Kerberos hosts, and are thus similar to the krb5_krbhst_init() functions. However,
     since these functions returns all hosts in one go, they potentially have to do more lookups than necessary. These functions remain for com-
     patibility reasons.

     After a call to one of these functions, hostlist is a NULL terminated list of strings, pointing to the requested Kerberos hosts. These should
     be freed with krb5_free_krbhst() when done with.

EXAMPLES

     The following code will print the KDCs of the realm ``MY.REALM''.

	   char **hosts, **p;
	   krb5_get_krbhst(context, "MY.REALM", &hosts);
	   for(p = hosts; *p; p++)
	       printf("%s
", *p);
	   krb5_free_krbhst(context, hosts);
