These have also been places on the catalogue page so it can not be bought since these are characters that can be used for minor SQLinjection. The actual issue as stated in the error file, which I have copied and pasted on here is the variable is not defined, so I am guessing this is to do with defining the variable outside of the function or something along those lines. It should not have anything to do with the content which is inside the parameter. Thank you for your suggestion though.</blockquote>
