OnClick event to manipulate Control Source

On my form, I have 4 textboxes with record sources to theses fields in a query:
WithShipping: [TOTAL]+15
DaysOverDue: DateDiff("d",[DATEVER],Now())
LateFee: (IIf([DaysOverDue]>30,[TOTAL]*0.02/30*[DaysOverDue],0))
GrandTotal: [WithShipping]+[LateFee]

Now, my question is: I would like the user to use a OnClick event to change the late fee. Lets say the late fee totals to $73.23, and the Collector is talking to customer over the phone and tells customer he will change late fee to be only, say $25.00. I would like the GrandTotal to then change to reflect this. Now I realize this is probably way too complicated to easily do via a query or VBA, so any ideas or suggestions for a similiar solution would be very much appreciated.
Many kind thanks in advance,
John

What happens though if the collector agrees to change the late fee to $25 but the amount still remains unpaid for a month, for example? Would the collector have to go back and agree another amount or should the normal calculation come into effect?

I might create a new field in the table called something like OverrideFee. If this field is not blank, use the field - otherwise use the calculation.

Nope, the collector wouldn't have to go back and agree to another amount. That would basically be like a calculator on the form that does the work for the collector. Oh, but I forgot to mention, I'd need the report that the Collector would print from that form, to reflect the same changes. Ahhhhhhh, so in the Override field, the new value would be entered, and then, use an onclick event to let form know to change which control sources it reads?

No, you wouldn't even need an OnClick event - you could use a nested IIf statement like this:

LateFee: (IIf([DaysOverDue]>30,IIf(Not IsNull([OVERRIDE]),[OVERRIDE],[TOTAL]*0.02/30*[DaysOverDue]),0))

Wow, damn, you come up with the most ingenious ideas!
Okay...I'm gonna be working with this thing; got my fingers crossed. Wish me luck. I think I know exactly where you're coming from!

Must be doing something wrong here...because the LateFee field is displaying nothing unless there's a value in the OverrideFee field.  Here's what I got so far:

Private Sub Form_Current()
If Me!OverrideFee.Value <> "" Then
Me!txtLateFee.ControlSource = "LateFee"
Else
Me!txtLateFee.ControlSource = "OverrideFee"
End If

Private Sub lblChgLateFee_Click()
Me!txtLateFee.ControlSource = "OverrideFee"
Me.txtLateFee.Enabled = True
Me.txtLateFee.Locked = False
Me.lblLateFeeOk.Visible = True
Me.lblChgLateFee.Visible = False
End Sub

Private Sub lblLateFeeOk_Click()
Me.lblChgLateFee.Visible = True
Me.lblLateFeeOk.Visible = False
Me!txtLateFee.ControlSource = "LateFee"
Me.txtLateFee.Enabled = False
Me.txtLateFee.Locked = True
End Sub

Try:
If IsNull(Me!OverrideFee) Then
Me!txtLateFee.ControlSource = "LateFee"
Else
Me!txtLateFee.ControlSource = "OverrideFee"
End If

You've actually got the logic the wrong way round - you want to display the LateFee if the OverrideFee is null (or blank), rather than the other way round :)

I'm a bit dislexic, lol--thanks for transposing my logic there! Now...I'm about stumped here:
LateFee: (IIf([DaysOverDue]>30,IIf(Not IsNull([OVERRIDE]),[OVERRIDE],[TOTAL]*0.02/30*[DaysOverDue]),0))
That LateFee is already in the query, so I'm wondering if should create another field in that query naming it something like LateOverrideFee or create an entirely different query. Not too sure what you mean about nested IIf statement. You mean creating another query and calling it from my LateFee query?  Or, if I just add it to existing query, reference it instead of LateFee if [OverrideFee] is not null? Hmmmmnnn...very interesting! Points increased to 350.

If you've already got the nested IIf in the expression, the LateFee field will always show the correct amount - that is to say, if the item is not overdue, it shows 0. If it is, and there is an Override fee, it shows the override fee otherwise it shows the normal calculation. You don't need any code at all - just bind the textbox to the LateFee field and let the expression handle the calculation for you.
