I've built an application off of a simple list in SharePoint.  The list has four fields:

• Title - single line of text
• Message - multiline text
• SendToGroup - choice
• SendNow - boolean

The SharePoint list has a default value for the boolean field of No.  That's by design; I don't want this thing sending new messages unless that's a conscious choice.

Anyway.  Regardless of what I select on the form, the new item comes in with the default value for that field.  If I check the SendNow box to indicate I want the broadcast sent immediately, that selection is ignored and the default value is used.  The same is true if I set the default value to Yes and uncheck the box in the new item form.

Anyone have any ideas?
