HELP! Unable to Scrap from a drop down menu

I'm having difficulty in scraping from a drop down menu.

Can someone suggest a fix for having the scrape pull? Thank you!

{"_id":"tee","startUrl":["http://nigeriapostcode.com.ng/"],"selectors":[{"id":"state","type":"SelectorElementClick","selector":"tr:contains('State') select.field","parentSelectors":["_root"],"multiple":false,"delay":"2000","clickElementSelector":"tr:contains('State') select.field","clickType":"clickOnce","discardInitialElements":false,"clickElementUniquenessType":"uniqueHTMLText"},{"id":"Town","type":"SelectorElementClick","selector":"td#town_td select.field","parentSelectors":["_root"],"multiple":false,"delay":"","clickElementSelector":"td#town_td select.field","clickType":"clickOnce","discardInitialElements":false,"clickElementUniquenessType":"uniqueHTMLText"},{"id":"Area","type":"SelectorElementClick","selector":"tr:contains('Area') select.field","parentSelectors":["_root"],"multiple":false,"delay":"","clickElementSelector":"tr:contains('Area') select.field","clickType":"clickOnce","discardInitialElements":false,"clickElementUniquenessType":"uniqueHTMLText"},{"id":"Get","type":"SelectorElementClick","selector":"button","parentSelectors":["_root"],"multiple":false,"delay":"","clickElementSelector":"button","clickType":"clickOnce","discardInitialElements":false,"clickElementUniquenessType":"uniqueHTMLText"},{"id":"result","type":"SelectorText","selector":"div#postcode_result > div:nth-of-type(1) > div","parentSelectors":["_root"],"multiple":false,"regex":"","delay":""}]}

I need assistance please !!!

Hello,

this is an interesting exercice but I organised the scrape differently.

At each step, I succeded to get the different "Data Preview" for state, town, Area, Street.

At the end I uses a "Element clic " selector but I failed. If a specialist could help us, that would be fine

The solution should be not far from this:

{"_id":"test_nigerian_postcode","startUrl":["http://nigeriapostcode.com.ng/"],"selectors":[{"id":"state","type":"SelectorPopupLink","selector":"select.field","parentSelectors":["_root"],"multiple":true,"delay":"2000"},{"id":"town","type":"SelectorPopupLink","selector":"tr:contains('Town') select.field","parentSelectors":["state"],"multiple":true,"delay":"2000"},{"id":"area","type":"SelectorPopupLink","selector":"tr:contains('Area') select.field","parentSelectors":["town"],"multiple":true,"delay":"2000"},{"id":"street","type":"SelectorPopupLink","selector":"tr:contains('Street') select.field","parentSelectors":["area"],"multiple":true,"delay":"2000"},{"id":"get_pc","type":"SelectorElementClick","selector":"div#content div.box","parentSelectors":["street"],"multiple":false,"delay":"2000","clickElementSelector":"button","clickType":"clickOnce","discardInitialElements":true,"clickElementUniquenessType":"uniqueText"},{"id":"code","type":"SelectorText","selector":"div#postcode_result > div:nth-of-type(1) div div:nth-of-type(1)","parentSelectors":["get_pc"],"multiple":false,"regex":"","delay":0}]}

Someone should please help me with this.
