Use the debugger to check the results as it may be that the query is not returning a value, I think dates for Access need to be enclosed by #'s.

rs3.Open "select sum(TotalHours) as thrs from tbldwardetails where employeesid =" & Val(empids) & " And dwardate=#" & Val(dwardate) & "#", db, 3, 3

Also not sure why you you Val() the date, the date in this case is not a number but a string.

Not a solution to your question, but another problem you have.
Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.
