I have a workbook that uses the values that a user had entered into 3 cells to calculate multiple other charts/diagrams on multiple sheets within the workbook. Each sheet would show what the user had entered in the 3 cells to allow them to see what is being used to calculate each table. Is it possible to link these cells so that the user can change the 3 values without having to go back to where he originally entered the 3 values?

For example, a user has entered in 3 values in Sheet 1. A formula in Sheet 2 displays what is entered by the user and uses these calls in Sheet 2 for calculations. When the user wants to change the three values, he would have to navigate to Sheet 1 and enter in the new values to have the workbook recalculate all the tables. Is there a way to link the three cells from Sheet 1 and Sheet 2 so when the user is on Sheet 2, he has the opportunity to change the values on the current Sheet without having to navigate to Sheet 1 to do so?
