FAQ: How to change the cell color depending on the range of numerical value in the Screen Index
## Answer
Use "「Server Script」" and "「Style」".
---
## Overview
In "「Server Script」", assign "Cell CSS" according to the range of "「Numerical Value Column」" specified on "「Screen Index」" and change the background color of the cell.

## Operation Procedure
1. Create a "「Table」".
1. Enable "NumC (NumC)" in "「List Screen Column Settings」".
1. "Create new" the following "「Server Script」". For "「Condition」", select "Before Row Display".
1. "Create new" the following "「Style」". For "Destination", select "Index".
## Script
##### JavaScript (Server Script)
```
// If the value of number C is less than 10,000, the background will be changed to red, if it is between 20,000 and 30,000, the background will be changed to yellow, and if it is 30,000 or more, the background will be changed to blue. The background color will be specified using a style that has been set in advance.
const total = model.NumC;
if (total < 10000) {
columns.NumC.ExtendedCellCss = 'cell-blue';
} else if (total >= 10000 && total < 30000) {
columns.NumC.ExtendedCellCss = 'cell-yellow';
} else if (total >= 30000) {
columns.NumC.ExtendedCellCss = 'cell-red';
}
```
