I haven't been able to figure out how to create a foreign key data type. All the examples of how to link tables does not show the creation of the foreign key it is already there.

Thanks,

Never mind, I figured it out....

Hi There and welcome
Your question is usually one of the first that we need help with

drag the foreign key data type to your table (the same as text, int etc)

in the far right column you will see a blank box (dont worry about it for now)

now drop the left hand slider panes to show you your tables

drag your table from the left hand slider and drop it into the blank box mentioned above

Hope it helps
