This is wierd. When I build my entire app, I don't get the ambiguous date error message - it appears to work correctly. This may tie into the other question I posted about adding a new form to the system making my specify full path names.

>You can set the text box values to {} to signify an empty date (either in the init or on the property page "value" property. Then the data type will be a date (use DTOC to convert back to a string). Then the following code should work:

>IF NOT EMPTY(THISFORM.txtStartDate.Value)
> lcWhere = "AND invpost.invdate>={"+DTOC(THISFORM.txtStartDate.Value)+"}"
>ENDIF
>
>IF NOT EMPTY(THISFORM.txtEndDate.Value)
>  lcWhere = lcWhere + " AND invpost.invdate<={"+ ;
>    DTOC(THISFORM.txtEndDate.Value) + "}"

>>I have a form that has optional date range textboxes on it - start date and end date. The data in those fields is text since I could not figure out how to make it a date datatype. I am building a SELECT statement, but since this field is optional, I figure I must build a string for my where clause and then put it in the select. I cannot figure out how to get the where clause to work. Any help is greatly appreciated.
