Not entirely sure what you mean but try this for the checkbox code

Private Sub CheckBox1_Click()
If CheckBox1.Value = True Then
Range("A1").Value = "1"
End If
End Sub

Tried it with a userform I'm woking on and it put a 1 on cell A1.
Hope that's what you're after.

I am creating a form that I wish to force users to enter in the
information correctly.

I have added checkboxes for them to click when they have checked their
inputs however I have a problem whose answer eludes me.

I have a cell that is validated with an in-cell dropdown list. If this
= "Yes" the I want to force the next cell down to be greater than "1".
I have been told to use an event triggered by the clicking of the
checkbox to to validate this cell.

any help will be much appreciated.
