Yeah, it looks like a gambling app.

At the time I didn’t pay attention to his code, anyway it is his account that is in jeopardy

The + (add) accepts numbers and Strings which only contain a number.

0.12345 - GOOD
“It is 5.6/7” or “5+6-3” - BAD

I have the same problem.

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.
