Do you mean you want the portal to have more rows to fill the tab control, or do you mean you always want blank rows at the bottom (or top)?
The screenshot shows you in Find Mode.
The find mode was just so I could capture a screenshot without personal data being seen.
I want to add more rows beneath the field that is marked 5/23/2017. I have data to enter beneath these rows but it always defaults to 8 rows. I'd like to have at least 15 rows.
Sounds like you don't have a portal. Sounds like you need a portal. I suggest reading up on portals in FileMaker help, in this forum and in any training materials that you have.
With a portal, you can add as many rows of data to that section as you need with a scroll bar to scroll through them should the number of rows exceed the available space on your layout.
What you have now appears to have been set up by defining more and more fields in your layout's underlying table, that's not a good way to go with this kind of data, a related table where each row is a record in that related table that is then displayed in a portal will work much better.
First, thank you so much for responding. I followed the instructions for
working with portals but the computer isn't responding as if the
rows/fields is a portal. I'm still researching it.
Feel free to post screen shots and more detailed descriptions of what you did if you'd like more assistance.
