How to pass a filter value into text box on form using VBA code

I have a form with a button on it that opens another form and passes a string value to it. On the 2nd form, I have an add new record button and I need to update a field ([Site]) on the "new record" form with the filter'd string value. Here's what I have now but the problem is it passes the whole filter string and not just the value that was used to filter the form. I have been stuck on this for a couple hours. Help! Access 2000.

Private Sub Command2_Click()
On Error GoTo Err_Command2_Click

Dim stLinkCriteria As String

    stLinkCriteria = Me.Filter
             
                   
    DoCmd.GoToRecord , , acNewRec
   
    Me![Site] = stLinkCriteria
    Me!LotID.Locked = False

Exit_Command2_Click:
    Exit Sub

Err_Command2_Click:
    MsgBox Err.Description
    Resume Exit_Command2_Click
   
End Sub

' passes a string value to it'
Is this relevant to the question?
If it is, then what does contain (example please).

so you want to give you new record the parameter of the Filter ?

how can you be sure, that the user has not filtered twice ?
on which field has te user filtered ?

waht you can do: Extract the last piece of the filter-string with the Split function and take the max-Index, which should give you the last "word" inthe filter string

A string is passed to the second form, for instance "Woodview Estates" and if there are any records that are related to it, they are filtered on the second form. If there are no records or they need to add a new record, they select the add record button and I want the value "Woodview Estates" to update a field on the form called "Site". The value "Woodview Estates" is visible in the properties of the form under filter [Site]='Woodview Estates'

I want the site field to contain Woodview Estates and not [Site]='Woodview Estates' like it contains now.

I would pass the string value as an open argument so you can use it again:

DoCmd.OpenForm "yourFormName", OpenArgs:="string_value"

on the form:

Private Sub Command2_Click()
On Error GoTo Err_Command2_Click

    DoCmd.GoToRecord , , acNewRec
   
    Me![Site] = Me.OpenArgs
    Me!LotID.Locked = False

Exit_Command2_Click:
    Exit Sub

Err_Command2_Click:
    MsgBox Err.Description
    Resume Exit_Command2_Click    
End Sub

Yes, I want to give the field [Site] on the new record the parameter of the filter.

Users will not be allowed to filter on their own. The button on the first page is automatically filtering the 2nd form for them.

Can I use the split function to pull out the text that I want ex.

Woodview Estates

if this will be constant, you can extraxt tha directly:

stLinkCriteria = Mid$(Me.Filter,9,Len(Me.Filter)-9)

maybe the last should be 10 or 8 , just look

The filter value won't always be the same. But the form will always be filtered by only once when it is pulled up. It all depends on what record the first form is on. If they happen to be on a different record on the first form, for instance "Valley View Estates", that value will be what is passed as the filter to the second form when they click the button.

Again though, the 2nd form is only filtered once based on the first form and the end users will not be allowed to set their own filters.

Thanks for the help. It was probably an easy one but I don't do enough VBA as I should be with Access. Here is the code for the first form.

    Dim stDocName As String
    Dim stLinkCriteria As String
    Dim sitepass As String
   
    stDocName = "frmAddLots"
   
    stLinkCriteria = "[Site]=" & "'" & Me![SiteName] & "'"
    sitepass = Me![SiteName]
   
    DoCmd.OpenForm stDocName, , , stLinkCriteria, OpenArgs:=sitepass

AND THE SECOND FORM

DoCmd.GoToRecord , , acNewRec
   
    Me![Site] = Me.OpenArgs
    Me!LotID.Locked = False

you can assemble your forms filter by a condition and a value, i.e:
 
  Filtervalue=100
  me.filter="YourField >= " & Filtervalue

later you use
Me![Site] = Filtervalue
