I have developed a form, published it etc.
On it are two buttons which when clicked will run the following code.

Sub CommandButton2_Click()
myItem.subject = "Yes I will be attending"
myItem.to = "
myItem.send
msgbox "Thank you for your response"
End Sub

Sub CommandButton1_Click()
item.subject = "No I will not be attending"
Item.to = "
Item.send
msgbox "Thank you for your response"
End Sub

When sent to someone using Outlook 2000, it runs fine (assuming
security allows it) and clicking each button sends an email and
displays the alert box.
When sent to someone using Outlook 2003, it doesn't run the code, even
with security set to low.
However, when testing it under 2003 it works.
Any ideas as to why 2003 recipients can't run the code?
