It should be " that the first item was set to 1" but I create a test for 01 and its 01.1 normal and true. But when i create new file for 02 it not be 02.01. its 02.02. I think its continue from name TST file.https://www.infopathdev.com:443/forums/thread/121183.aspxTue, 25 Jun 2019 21:57:42 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:121183Hilary Stoupa0https://www.infopathdev.com:443/forums/thread/121183.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=121183The reset number rule was in case there were no result returned from the query, so that the first item was set to 1. I don't recall dealing with non-numbers like 01.1 and 02.01 in your original form. I'm not sure how the max function will work with those.https://www.infopathdev.com:443/forums/thread/121182.aspxTue, 25 Jun 2019 21:50:44 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:121182Fatihteke0https://www.infopathdev.com:443/forums/thread/121182.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=121182Hello Hilary, Its always get same number now. For example When i try 01 its 01.2 (normal because there is already 01.1) but when i try 02 its 02.2 ( there is no 02.01) it should be create new. you create "Reset Number" For this. But i think i broke it :(https://www.infopathdev.com:443/forums/thread/121180.aspxMon, 24 Jun 2019 23:24:12 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:121180Hilary Stoupa0https://www.infopathdev.com:443/forums/thread/121180.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=121180Try this one. In the rule that is to set the number field, you were using the main data source field rather than the secondary.https://www.infopathdev.com:443/forums/thread/121178.aspxMon, 24 Jun 2019 18:27:25 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:121178Fatihteke0https://www.infopathdev.com:443/forums/thread/121178.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=121178Hello Hilary, I changed design and something form which we created before.
