Hi GreenvilleGuy,

I just wanted to point out that if you want your grids to display properly, you need to click on the 'Code' button just before entering the grid and then click on it again after you have entered the grid. When you click on the button the first time it will appear in your window as the text 'code' enclosed in square brackets and then when you click on it a 2nd time it will appear as '/code' (also enclosed in square brackets).

To see how your post will look before posting it, click on the 'Preview' button before clicking on the 'Submit' button.

I also wanted to mention that ZeroAssoluto (aka Gianni) had already posted your solution. In order to see his solutions, you just need to point your mouse over the beginning of that box labelled 'Quote', right-click and hold it down, and then drag the mouse over the rest of the box. Some posters present their solutions this way (i.e. with white text on a white background) in order to avoid accidentally giving away the solutions.

I just thought you'd like to know. Thanks and keep up the great work, Don.
