Got this out of Excel help, follow it through and you will be fine.
Record a macro
1 On the Tools menu, point to Macro, and then click Record.
2 In the Macro name box, enter a name for the macro.
The first character of the macro name must be a letter. Other characters can
be letters, numbers, or underscore characters. Spaces are not allowed in a
macro name; an underscore character works well as a word separator.
3 To run the macro by pressing a keyboard shortcut key, enter a letter in
the Shortcut key box. You can use CTRL+ letter (for lowercase letters) or
CTRL+SHIFT+ letter (for uppercase letters), where letter is any letter key
on the keyboard. The shortcut key letter you use cannot be a number or
special character. The shortcut key will override any default Microsoft
Excel shortcut keys while the workbook that contains the macro is open.
4 In the Store macro in box, click the location where you want to store the
macro.
If you want a macro to be available whenever you use Microsoft Excel, store
the macro in the Personal Macro Workbook in the XLStart folder.
To include a description of the macro, type the description in the
Description box.
5 Click OK.
If you select cells while running a macro, the macro will select the same
cells regardless of which cell is first selected because it records absolute
cell references. If you want a macro to select cells regardless of the
position of the active cell when you run the macro, set the macro recorder
to record relative cell references. On the Stop Recording toolbar, click
Relative Reference . Microsoft Excel will continue to record macros with
relative references until you quit Microsoft Excel or until you click
Relative Reference
again.
6 Carry out the actions you want to record.
7 On the Stop Recording toolbar, click Stop Recording .
Tip If you want a macro to select a specific cell, perform an action, and
then select another cell relative to the active cell, you can mix the use of
relative and absolute references when you record the macro. To record a
macro by using relative references, make sure that Relative Reference is
pressed in. To record with absolute references, make sure Relative Reference
is not pressed in.
