A few comments;
Dont need CSV can read excel or Libre calc directly, search here for "Alan excel.lsp" it has lots of functions that you can use. Happy to discuss further.
Yes or No, there is a Acet function "yes no", do a google, or you can use this radio buttons program which can be used in any code, there is a yes or no example at the top of the code. The other is to use a INITGET method. Multi radio buttons.lsp
Ps why not add a point number in excel so easy to just do 1 & 2 column "A" then drag down to last cell. A Ps ps the code can update your excel re a point number adding to column "A".
