here we go:

Dim rs1 As DAO.Recordset
Dim strSQL1 As String     
strSQL1 = "SELECT Fullpart, qty, date FROM PARTS WHERE Date<= #[Enter Ending Date (format mm/dd/yyyy)]#;" 
Set rs1 = CurrentDb.OpenRecordset(strSQL1)

or like this:

Dim rs1 As DAO.Recordset
Dim strSQL1 As String   
dim Enddate as String 
EndDate= inputbox("Enter Ending Date (format mm/dd/yyyy)", "Parameter for Query")  
strSQL1 = "SELECT Fullpart, qty, date FROM PARTS WHERE Date<= #" & EndDate & "#" 
Set rs1 = CurrentDb.OpenRecordset(strSQL1)

It is to say you cannot create a query with a parameter and open that query in code and expect to be asked for the parameter.  You have the option of using an input box as per AngelIII's suggestion, or calling a sub or a function in which you pass the endDate as in:

Public Function OpenRS(myDate as String)

Dim db as DAO.Database, rs as DAO.Recordset, mySQL as String
myDate="#" & myDate & "#"
mySQL="SELECT Fullpart, qty, date FROM PARTS WHERE [Date] <= " & MyDate
set rs = db.openrecordset(mySQL,dbOpenDynaset)

I believe you need the dbOpenDynaset as you will otherwise generate an error saying it could not find mySQL (expanded as a string).

If you're doing it in VBA, just build a string in VBA

You could move the inputbox before the string build, store to a temp string, check if its "". If so don't bother opening recordset.

Just be sure to use the #s to indicate your entry is a number, not a string.

Dim rs1 As DAO.Recordset
Dim strSQL1 As String    
 
strSQL1 = "SELECT Fullpart, qty, date FROM PARTS WHERE Date<=#" & inputbox("Enter Ending Date") & "#"
 
Set rs1 = CurrentDb.OpenRecordset(strSQL1)
