I don't understand your first problem, I have had something similar with repeating groups going down the page when the containing subform doesn't allow page breaks, but I haven't had a problem going left top right, Seems strange that you can get one total working and not another.Tabbing can also be a bit of a problem.
But I think you will have to post your form somewhere and add a link to this thread. There are lots of places to host a file, a lot of people use Acrobat.com (just remmeber to publish/share it)
Thank you for responding! I have no idea if this link will work, I've never done this before.
The first trouble spot is under the DOS Date Range: It's the pair of date fields that are set to add instance when the second of them is changed.
The column addition problem is in the table with the nine columns.
Please let me know if my link doesn't work- I'll call IT and ask for help....
