When you have kidney disease, your kidneys are no longer able to remove waste effectively from your body or to balance your fluids. The build up of wastes can change the chemistry of your body causing some symptoms that you can feel, and others that you don't.
Reference to a range of cells is typically of the form (A1:A6), which specifies all the cells in the range A1 through to A6. A formula such as =SUM(A1:A6) would add all the cells specified and put the result in the cell containing the formula itself.
To use the function, enter =LEN(cell) in the formula bar and press Enter. In these examples, cell is the cell you want to count, such as B1. To count the characters in more than one cell, enter the formula, and then drag the fill handle across or down the range of cells you want to use. To count a total number of characters in several cells, use the SUM functions along with LEN. For example, =SUM((LEN(cell1),LEN(cell2),(LEN(cell3)))) . In this example, the LEN function counts the characters in each cell and the SUM function adds the counts.
