echo the actual query being run.

"INSERT INTO repplac VALUES (‘’,'$Sname’,'$Pname’,'$Pidno’,'$Psize’,'$Pcolour’,'$Pquantity’,'$Weblink’,'$Price’)"

and if the values are not correct then you need to trace back your code to the line where that incorrect value is set and fix it.

hint: names are case sensitive

thanks i did that , and was able to track where the problem was in the code
