Some years ago I sought the assistance of the Help Room to obtain a system for setting up a grid with National Lottery numbers and being able to quickly check the numbers which came up at each Draw.. A contributor supplied me with such a system and this has worked well - until last weekend when none of the numbers I entered were recorded on the grid. A friend runs a back up grid and he sent me a copy, but that didn't work either! Usually I am given a warning about the Macro I need to use in order to open the grid, but this does not now appear. I confess to having very little knowledge of Macros, but wonder if it is a case of re-installing them, but do not know how to do this!! My System is Windows XP and I use Microsoft Excel 2007 for operating the grid. Any help will be appreciated, as it is a lengthy business, crossing off lots of numbers after each draw!!!
