Thread: Cannot find symbol?

hey really strange error...help please.
this is my code

import javax.swing.JOptionPane;
 
class GearPumps
{
	public static void main(String[]args)
	{
 
	String input1;
	String input2;
	String input3;
	double gearw;
	double borediameter;
	double gearchambers;
	double gpm;
	double cir;
	int again;
 
		do
		{
			//This gets the input for the equations.
			input1 = JOptionPane.showInputDialog("Enter the gear width in Inches.");
			input2 = JOptionPane.showInputDialog("Enter the Bore Diameter.");
			input3 = JOptionPane.showInputDialog("Enter the distance across both Gear Chambers.");
 
 
			//converts the inputed strings to a double
 
			gearw = Double.parseDouble(input1);
			borediameter = Double.parseDouble(input2);
			gearchambers = Double.parseDouble(input3);
 
			//sets formulas for cubic inch revolution and gallons per minute;
			gpm =( 47.0 * gearw * ((2.0*borediameter)-gearchambers) * (gearchambers - borediameter)/2);
 
			cir = (6.0 * gearw ((2.0 * borediameter) -gearchambers) * (gearchambers - borediameter)/2);
 
			//displays results
			JOptionPane.showMessageDialog(null,"GPM: "+ gpm  + "CIR: "+cir);
 
 
			//ask user to go again.
			again = JOptionPane.showConfirmDialog(null, "Another calculation?");
 
		}
		while(again  == JOptionPane.YES_OPTION);
	}
}

and i get this error:
GearPumps.java:35: cannot find symbol
symbol : method gearw(double)
location: class GearPumps
cir = (6.0 * gearw ((2.0 * borediameter) -gearchambers) * (gearchambers - borediameter)/2);

Not strange at all ...look closely at the code

gearw ((//
vs
gearw  * ((

hm?
i didnt put // though, i have the ((

oooh i c my bad...didnt look closely enough. thank you!
