    I wish to open a form in database view showing only the data that has
    nothing in the date returned field.

    Currently this is the code i have but it is not working.

    Dim stDocName As String
    Dim stLinkCriteria As String

    stLinkCriteria = IsNull([Date Returned])
    stDocName = "Returnsform"
    DoCmd.OpenForm stDocName, acFormDS, , stLinkCriteria


    The problem is in the "stLinkCriteria...." line of code. It says the
    Database cannot find the field "|" reffered to in your expression. What
    code should i use or should i use a filter or a query to do this?

    Any Ideas..

    Add this line to your code, above the OpenForm line:
    Debug.Print stLinkCriteria
    You will see that your criteria string does not contain a valid expression.
    It will contains something like -1 (the value of True, if the expression is
    True) or 0.

    Now replace your 3rd line with:
    stLinkCriteria = "[Date Returned] Is Null"
    and see how you go.

    Cheers Allen, That worked perfect. Yet again you come to my rescue.
    Thanks
     
Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
