Make formula based on other formula blank

[Guest]

Is there a way to make a value in a text box, that is based on another text
box, blank and not always say "#error" ? I tried using an IIF statement but
it didn't work. I'm sure people run into these all the time. Thanks

txtbox1:

txtbox2:=DateSerial(year[txtbox1]....

When opening form... txtbox2 displays..."#error"

DateSerial must have numbers, not nulls, so try something like this:

=IIf(IsNumeric([txtbox1]) And IsNumeric([txtbox2]) And
IsNumeric([txtbox3])), DateSerial([txtbox1], [txtbox2], [txtbox3], Null)

 

[Guest]

=IIf(IsNull(txtBox1), Null, DateSerial(year[txtbox1]....)

Once again it works great!
