Validating excel cells
Use data validation to limit calculated cell to the Formula textbox. Then go to the Error Alert tab, and type the error warning you want in the Error message. Click OK, and the warning dialog will pop out if the values entered in the cells lead to the sum greater than 10.By default, the arrow of the data validation won’t show automatically.As we know, the Data Validation can limit values entered, but have you ever tried to limit the calculated results by using Data Validation function?For instance, here are three cells, A1, A2 and A3, what I need is to limit the sum of these three cells not greater than 10, if the value entered in the three cells lead to the sum greater than 10, a warning dialog pops out and stop entering.Validation rules can change cells font, style, size or border. For example, rules may highlight negative figures by printing them in red.Rules may also highlight maximum or minimum values, color values by their rank or catch duplicate entries.For example, if you want to change the color of all figures less than zero, select "Cell Value" and "less than" from the first two drop-down boxes.
