The question is still the same, but the title is rewritten as follows: My Javascript random function fails to generate valid responses

I'm making a simple random number generator game using JS and HTML. In this game you can set minimum and maximum values of random numbers. However, when setting the variables and recording the results, an impossible number appears. For example, if I set the minimum value to 50 and the maximum value to 100, it will show answers like 58650, 16750, or 31450. I noticed that the smallest number you set always appears at the end. I've tried changing the format and changing the code but nothing seems to work. Does anyone know a solution to this problem? Your help is greatly appreciated, thank you! !

Can PHP and MariaDB provide a more efficient solution for performing multiple inserts?

So I'm trying to build a small database to track the high scores of the pinball machines in our league. I have a table of users that only has an AIid column and a column containing their email address. Then I have a game table which is an AIid column, and the name of the machine. Since it is a many-to-many relationship, I created a third table called "scores" which contains user_id, game_id, and Score as columns. EDIT: Included reading code: $file=fopen('scores.txt','r')ordie

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
