ตระกูลซอฟต์แวร์สเปรดชีตของ Microsoft ที่มีเครื่องมือสำหรับการวิเคราะห์ ทำแผนภูมิ และสื่อสารข้อมูล
I am sure you're misunderstanding my question.
The problem is at the Microsoft Excel program I have in my computer. It does not show the options for negative numbers when I go to 'Format Cells'. When I'm there I find a blank box instead of 'options to display negative numbers' as it should be.
There is nothing about the 'number format' under Clock and Region section in Control Panel. I've been there to check and fixed it already.
Please try to solve the problem as I never expect this to happen in the genuine pack of Microsoft Office I purchased.
Attached with my reply is an image describing my problem with Excel.
