Hi,

I created a repeating table, and would like to include three columns (Library A) in it. One column, I would like it to be a textbox that read another field (Title) from another list (List B). If I create that first column as a drop down menu, I'm able to see all Titles in it. However, if I want to make it as a textbox that repeats within the table (i.e., there are 30 items in List B, and I would like all 30 items to show up repeating in the first column, as if I'm directly showing that column from List B onto my form). How can I do so?  

So - this isn't easy. It would be nice if it was. I'm guessing your intent is to have a table that the user can fill out - with just the first column pre-populated? If you just need to display the data, you can do that from the secondary data connection. If you need to store data that the user enters into the form, it is trickier. You might be able to use the default data technique outlined here: https://www.youtube.com/watch?v=W4ukzlaQBpM
