Unable to scrape

I just started using this tool. I wasn't able to get the scrapper to change categories on this site so I selected only one sub-category to test it out. Unfortunately I can not get it to produce any data. can you help?

Web Scraper version: 0.3.3
Chrome version: 63.0.3239.84
OS: Windows 10

Sitemap:
{"_id":"loloprice2","startUrl":["https://www.loloprice.com/tools-parts/gadgets/"],"selectors":[{"id":"item","type":"SelectorPopupLink","selector":"a.product-title","parentSelectors":["_root","pages"],"multiple":true,"delay":0},{"id":"code","type":"SelectorText","selector":"div.ty-product-block__sku span.ty-control-group__item","parentSelectors":["item"],"multiple":true,"regex":"","delay":0},{"id":"title","type":"SelectorText","selector":"h1.ty-product-block-title","parentSelectors":["item"],"multiple":true,"regex":"","delay":0},{"id":"price","type":"SelectorText","selector":"span#sec_discounted_price_5420.ty-price-num","parentSelectors":["item"],"multiple":true,"regex":"","delay":0},{"id":"qty","type":"SelectorText","selector":"span.ty-qty-in-stock","parentSelectors":["item"],"multiple":true,"regex":"","delay":0},{"id":"description","type":"SelectorText","selector":"div.cm-tabs-content","parentSelectors":["item"],"multiple":true,"regex":"","delay":0},{"id":"images","type":"SelectorImage","selector":"a.cm-gallery-item img.ty-pict","parentSelectors":["item"],"multiple":true,"delay":0},{"id":"pages","type":"SelectorLink","selector":"div.ty-column4:nth-of-type(n+21) a.product-title","parentSelectors":["_root"],"multiple":true,"delay":0}]}

Error Message:
scrapper finishes but no data is collected

To access error messages follow these steps:
1. Open chrome://extensions/ or go to manage extensions
2. Enable “developer mode” at the top right
3. Open Web Scrapers “background page”
4. A new popup window should appear.
5. Go to “Console” tab. You should see Web Scraper log messages and errors there.

You had to use link selector instead of popup link selector and your item attribute selectors were set to "multiple" where it was unnecessary. Here is an updated sitemap:

{"_id":"loloprice2","startUrl":["https://www.loloprice.com/tools-parts/gadgets/"],"selectors":[{"id":"item","type":"SelectorLink","selector":"a.product-title","parentSelectors":["_root","pages"],"multiple":true,"delay":0},{"id":"code","type":"SelectorText","selector":"div.ty-product-block__sku span.ty-control-group__item","parentSelectors":["item"],"multiple":false,"regex":"","delay":0},{"id":"title","type":"SelectorText","selector":"h1.ty-product-block-title","parentSelectors":["item"],"multiple":false,"regex":"","delay":0},{"id":"price","type":"SelectorText","selector":"span#sec_discounted_price_5420.ty-price-num","parentSelectors":["item"],"multiple":false,"regex":"","delay":0},{"id":"qty","type":"SelectorText","selector":"span.ty-qty-in-stock","parentSelectors":["item"],"multiple":false,"regex":"","delay":0},{"id":"description","type":"SelectorText","selector":"div.cm-tabs-content","parentSelectors":["item"],"multiple":false,"regex":"","delay":0},{"id":"images","type":"SelectorGroup","selector":"a.cm-gallery-item img.ty-pict","parentSelectors":["item"],"delay":0,"extractAttribute":"src"},{"id":"pages","type":"SelectorLink","selector":"div.ty-column4:nth-of-type(n+21) a.product-title","parentSelectors":["_root"],"multiple":true,"delay":0}]}

thank you. it works now.
