Power query - url with date

I am pulling data from a page that contains a date in the url.

Example http://abc.com/?startdate=11-05-2010

The date in the url is random and is displayed on abc's homepage.

I need to be able to first scrape abc.com homepage for the start date and then save that in a variable and append it to another query with the full url.

Query1 (abc.com)
scrapedStartDate = 11-05-2010

Query2 (abc.com/?startdate= scrapedStartDate)
