Намерих грешката  - The current furniture must be removed from the row in the table

https://pastebin.com/YWyqJeGS

88/100 error usually triggered when there is a problem with the "More Info"/"Less Info" functionality =>

When the "More Info" button is clicked, change button text from "More Info" to "Less Info" and style display of "class = hide" from "none " to "contents". The second <td> must have attribute colspan with value 3. When click "Less Info" button is clicked, change button text from "Less Info" to "More Info" and style from "contents " to "none".
