When my colleagues finish registered their contents, he received a notification like this

\<?xml version="1.0" encoding="UTF-8"?\>

\<doi\_batch\_diagnostic status=“completed” sp=“ds5”\>  
\<submission\_id\>1434685249\</submission\_id\>  
\<batch\_id\>\_1541995697\</batch\_id\>  
\<record\_diagnostic status=“Failure”\>  
10.29080/biotropic.2018.2.1.46 - 51  
DOI: 10.29080/biotropic.2018.2.1.46 - 51 , contains invalid characters  
\</record\_diagnostic\>  
\<batch\_data\>  
\<record\_count\>1\</record\_count\>  
\<success\_count\>0\</success\_count\>  
\<warning\_count\>0\</warning\_count\>  
\<failure\_count\>1\</failure\_count\>  
\</batch\_data\>  
\</doi\_batch\_diagnostic\>

What is the meaning of that and what should he do then? Thank you

Dear M. Ratodi,

I think space should be the problem. There should not be space between the characters or numbers. There is a space between 46 and 51. It should be 46-51 instead of 46 - 51.

Yes, Anjum is exactly right. The space is the problem. Your DOI suffix can be any alphanumeric string. Limited punctuation is allowed, the approved character set for DOI suffixes is: “a-z”, “A-Z”, “0-9” and “-.\_;()/”.
