In a private message you asked about assigning macros to buttons. Here is some general information on that subject:
Two button types are available plus you can use a Drawing Toolbar shape as a button.
1. Forms Button
Excel ToolBar: View - ToolBars - Forms, then drag the button to your sheet. You can re-position later. It will ask you for the macro to run, so it easier if the macro is built first.
Right click "Format Control" to edit font color and text.
You can not change the background color of a Forms button, just the text color.
2. Controls Button
Excel ToolBar: View - ToolBars - Controls, drag...
This button when Right-Clicked (in Design Mode) has the "view code" option which opens the click event for that button. These buttons have much more flexability and the button colors can be changed, unlike the Forms button.
Color and other options are setup in the Properties Dialog box. At first it is a little confusing but the changes can be worthwhile.
To change the Text of a Control button, right click, under CommandButton Object, choose Edit.
Must use "Design Mode" to set this button up, then turn off design mode to use the button.
3. Shapes Button, (My favorite)
You might condider using a Shapes Button.
You can build this button from the Drawing Toolbar.
Right click the ToolBar area: Click Drawing to open the Drawing Toolbar.
Click AutoShapes
Click "Basic Shapes" | Click Bevel, then drag to size on your worksheet
You can easily customize this 3-D button by right clicking it and choosing Format AutoShape…
You can add color, shadows, change font, adjust properties, etc.
You assign macros to this button just like you do with a Forms button, right click and choose "Assign Macro".
No need to use design mode. This button is much easier to setup than a Control Button.
