Hi all,
I plan to use automate to create auto increment from 1 based on the list rows, and from 1 to 256 rows the automate is exactly right. However, when the number reaches 257 no matter how many times I add rows it will always be 257 and never increase to 258,259......
Can you help me to solve this problem? Thanks so much!

The Compose is
length(outputs('List_rows_present_in_a_table')?['body/value'])
The variable is
concat('HKTW-DN-',add(1,length(outputs('List_rows_present_in_a_table')?['body/value'])))
The wrong result is
