For the code that is spliced ​​and then output like this, it is easy to miss single and double quotation marks. I suggest that it is better to divide it into two steps, first splice it into a string, and then output it. It is more obvious to find the error point in this way.

Didn’t you notice that &num is not enclosed in double quotes? This editor has them all colored for you.

Look carefully at the splicing of your strings and variables
