Thank you Andreas for your reply .
I can live with the second issue, it will not affect the webste mechanism,
but regarding to your advice for the API cods ,
i did checked that code and i failed to make it work , the reason is me NOT the code .
that’s why i requested if possible one of wix experts can provide to me a complete code for my example. wich will do the qury & count function then it will show the result in the text box. and i will change in this code for different datasets categories
