Follow the directions in the project. Type a number with as many digits as you'd like, but don't use commas. For example, if you want to add 9,000, write it as 9000, or else it will not read the number. Click the clear button to set the variable back to 0.
Thanks to @Mrcakeyman89 for the idea. When I looked at his project, I just decided to make another version of his project, the only thing is that the coding in my project is more simpler.
