Variables in VBA

After a bit of play with an online Spreadsheet, first up this morning is finding out exactly what variables are in VBA, and why we should declare them!

If you're really keen, you could do a google search for "vba excel variables" and see if you can find something readable!

This morning's challenge is to see if you can find out why my VBA code doesn't work! (I'll supply the code in class)
