Link two databases on one page

Hi there, I have 2 database(database A and B ) indicating 2 different sets of info. I created 2 tables (say table 1 and table 2) for each database on one page. But when I link database A to table 1, there is only database A options for table 2. How can I solve this? please help, thanks.

Have you created a dataset for each database? If you did please send the editor’s URL.
