    Hello,
    I'm trying to use the amazon scraper to retrieve product data but always get this error:

    JavaScript error: TypeError: Cannot read property 'push' of undefined at Parser.pushProduct


    using variables like $product.$i.title and the likes.

    What am i doing wrong?

    Thanks!

    You have several errors at once:
    - if you specify a template in the General format of the result, you need to refer to the number of the parser you are using, for example $p1
    - for output of arrays, you need to use the .format method
    So the correct template will look like this:
    Code:
    $p1.products.format('$title\n')
    I recommend you read these articles in the Documentation:
    http://en.a-parser.com/wiki/results-representation/#arrays-of-results
    https://en.a-parser.com/wiki/result-format/
    http://en.a-parser.com/wiki/template-toolkit/#format-method-for-arrays

    Thanks a lot, i thought it must have been me. I looked through the wiki but could not find a solution. I have not been careful enough, so i thank you for your help!
