Some text boxes on Unbound form not appearing in intellisense

I have a form that I initially created with the form wizard based on a table so would be sure to capture all the approrpiate fields.  I delete the control source and renamed all the text boxes from their original column names to the column name plus txt.  That is, Tast control is now txtTask.  However, none of these text boxes appear when I write the vba to update back to the table.  That is, when I set, say rst!Task = Me.txtTask, txtTask does not appear and it says it does not exist.  However, if I create a fresh text control and rename it, then it does appear.  I doh't want to have to create all these text boxes and I simply do not understand why they would not appear.  I cleared the record source for the form as I want it to be unbound until the save code is run.
