Hi..Ron..

I am sending you the following code..which is passing that global variables value into the method "mortgageSelect()" and thus you will take these value into your method "rates" and "periods" variable ..This will solve your problem....Full code is as given below...If still your problem is unsolved then please send full detail regarding your problem so that I can better understand your problem.. Try this code...
ThankYou...

Code is :
import java.io.*;
public class GlobalArray {

GlobalArray(){}

public void mortgageSelect(double rate,int period) throws IOException{

double rates=rate;
int periods=period;
double mRate [] = {5.35, 5.5, 5.75};
int mTerm [] = {7, 15, 30};
int choice;
BufferedReader dataIn = new BufferedReader(new InputStreamReader(System.in));

/* selection 1 = 7 year loan
* selection 2 = 15 year loan
* selection 3 = 30 year loan
*/

System.out.print("Loan Options\n");
System.out.print("1. 7 Year Loan at 5.35% Interest\n");
System.out.print("2. 15 Year Loan at 5.5% Interest\n");
System.out.print("3. 30 Year Loan at 5.75% Interest\n");
System.out.print("\nPlease select from the loan options listed above: ");

choice = Integer.parseInt(dataIn.readLine());

if (choice >= 1 && choice < 4)
{
switch (choice)
{

case 1:
System.out.print("You have opted for a 7 year loan\n");
rates = mRate[0];
periods = mTerm[0];
System.out.printf("The interest rate of%6.2f %6.2f percent will be applied for a period of%2d %2d years", rate, mRate[0], periods, mTerm[0]);
break;
case 2:
System.out.print("You have opted for a 15 year loan\n");
rates = mRate[1];
periods = mTerm[1];
System.out.printf("The interest rate of%6.2f percent will be applied for a period of%2d years", mRate[1], mTerm[1]);
break;

case 3:
System.out.print("You have opted for a 30 year loan\n");
rates = mRate[2];
periods = mTerm[2];
System.out.printf("The interest rate of%6.2f percent will be applied for a period of%2d years", mRate[2], mTerm[2]);
break;
}
}
else
{
System.out.printf("The option you selected is not valid\n");// need to make sure when this displays the payment history is not displayed
}
}
public static void main(String args[]) throws IOException{

double rate=0.0;
int period=0;
GlobalArray ga= new GlobalArray();
ga.mortgageSelect(rate,period);
}
}
