I have a question on a form that the only answer would be a single number, or a list of numbers. "1" or "1,3,4,17,26", etc. Is it possible to not allow alpha characters in the field. I'm trying to prevent an answer such as "all lines", when the answer should be 1-10 or 1,2,3,4,5,6,7,8,9,10.

Cognito Forms supports repeating sections to capture repeating data. It also supports exporting entry data to an Excel spreadsheet with one sheet containing the main entry data and additional sheets for each repeating section. CSV export is not currently supported due to the requirement of exporting hierarchical data like this.
Anyone can sign up for free and create an organization account, but currently this is limited to one organization per user and one user per organization. This limitation will disappear in the coming months as new features are added.

When using a phone field set to the US, your phone number will look like a line of numbers until you click out of the field.
Then field will then auto verify that all characters are numbers and that 10 characters have been added.
If you have fewer then 10 characters or have a non-numeric character you will receive an error message. This will only happen when the field is set to "US".
For phone fields set to international we do not have validation. This is because of the wide variation between phone numbers in difference countries. We are considering ways to incorporate validation for this, like using Google's phone number library.

We will be releasing support for custom text format validation in Cognito Forms next week. You can track the release of this feature on our Idea Board. This will allow you to simply select a predefined format, like Numeric, enter simple masks, or even use custom regular expressions!
In the meantime, you can set up a Custom Error message on your Text field to display an error when a user enters in an alpha character. You can use the following calculation to do this, you will just need to change 'TextField' to reflect your own field's label.
