Accessing Dynamic URL with multiple conditions

[casey_autogator]

Want to access some table data off html page(s) but there are multiple constraints. I know how to loop through a single basic variable situation, but not sure how to do this one? 

Constraints are:

1. The url needs to be dynamic (this isn't too difficult)
2. Part of the FROM statement also needs to be dynamic 
3. If there are no page results, the URL changes to a default URL that kills the loop

For each x ....

FROM [.......)]
(url is [https://dynamic_url/], html, codepage is 28591, embedded labels, table is @$(dynamic table #)); 
next x;
