Hello,

Thank you for reaching out here in the DocuSign Community.

Does this /^\\d+$/ pattern works or this one /^[0-9]{0,}$/ ?

Let us know if you need further assistance with this.

Thanks @Christopher Alpizar​ - I tried both and tested on the Preview. Neither worked. Everything I entered wasn't accepted.

eg 123456789 (which should be valid as 9 digits, all numbers with no spaces) but it wouldn't proceed

Hello,

Does this one work^[0-9]+$ ? the system should not allow the recipient to complete the envelope if there is a space or letter in the text field.

Yes - thanks that one's has done the job. (Maybe it was the / at the end of the other two patterns which caused them not to work)

I see this works for 4 Numbers but what If I need them random, this is in order only.
