Could https://bytes.com/topic/access/answers/638383-when-dsum-null-get-error you explain the code though? I'm curious what it does. Apr 26 '07 #3 reply 100+ P: 493 AccessIdiot Wait nevermind - it says #Error when I go to a new record but as soon as I start filling it in it changes to 0. I guess I had to wait until the Entrainment_ID actually incremented. I'm still interested in what the code means though! :) Thanks!

The nz() function can be put around any expression to capture a null return. Expand|Select|Wrap|Line Numbers nz(expresssion,valueifnull) Apr 26 '07 #5 reply 100+ P: 493 AccessIdiot Thanks!

The field "Free" is from a query having multiple parameter criteria and I am confused on how to pull this information into my form. I have looked up the syntax for the DSum function, but when incorporating it into the ms access dsum calculated text box control, it either gives me a (flashing #Error box) or and stagnet (#Error box).
