On which line? Remember a title is not meant to hold a question or an entire error message; it has to summarize briefly the issue.<br><br>
In your post, you should show the entire error message, line number should be indicated. And I guess the first line of your stored procedure is missing.
You seem to have more than one record with the same reg_no in your table.

Solution 1

set @count =(select srno from mous_info where reg_no = @reg_no)+1
This query is returning more than one value.

Use top to restrict to the first value e.g.
set @count =(select top srno from mous_info where reg_no = @reg_no)+1

Solution 2

from ur code

SQL

set @count =(select srno from mous_info where reg_no = @reg_no)+1

make sure 'select srno from mous_info where reg_no = @reg_no' returns single value
if the query returns more than one rows ,u need to correct it.
good luck ;-)

this code may work try

SQL

set @count =(select MAX(srno) from mous_info where reg_no = @reg_no)+1
