How to use Fast Formulas Spreadsheets
The tabs at the bottom of the spreadsheet contain different subjects.
Click on one of the tabs to display the subject that interests you.
Enter values into the light blue colored cells.
When you have entered values into the cells, formula results
appear in cells with red borders.
Help Using Spreadsheet Tabs
The spreadsheet tabs in Microsoft Excel are located at the bottom-left side.
To switch between sheets in a workbook, click the sheet tab for the sheet
you want to work on.
If you don't see the tab you want, click the tab scrolling buttons to display
the tab. Then click the desired tab.
Protected Cells
When you attempt to change cells that are not light blue-colored,
a message box appears, indicating that the sheet is protected.
The sheets are "protected" so that they are not accidentally
disturbed in unintended ways.
However, if you are comfortable working with formulas in MS Excel, you may
wish to edit the formulas to adapt them to other uses. You can easily disable
the protection feature as follows:
1 Select the tab that you wish to "Un-Protect"
2 Click the Tools menu, and choose
the Protection menu item and then
click "Unprotect Sheet..."
3 The sheet is now unprotected, allowing
you to make any changes you wish.
BE CAREFUL!
You can easily "re-protect" a sheet that you have unprotected, as follows:
1 Select the tab that you wish to protect
2 Click the Tools menu, and choose the Protection menu item and then
click "Protect Sheet..."
3 To protect the sheet without requiring a password to unprotect it later,
click the OK button.
To protect the sheet so that a password is required to unprotect it later,
type a password into the box, and then click the OK button.
DON'T FORGET THAT PASSWORD! WRITE IT DOWN SOMEWHERE.
Fast Formulas can not rescue you from forgotten passwords!
