change default value of a textbox

[bbxrider]

I have a textbox with a default value of Path where I write files.
from time to time the default path needs to be changed. so I set up button to set the
default value to whatever the current content of the textbox is, eg, the user can change it.
but can't seem to save the new default value
what I have tried

Private Sub Command29_Click()
Dim newText As String
Text27.SetFocus
newText = Text27.Text
Text27.DefaultValue = Chr$(34) & newText & Chr$(34)
DoCmd.Save
MsgBox "Default Folder for reports has been changed to: " & newText

posts that show changing hard copy text have default = """new value""" indicating you need to supply the quotes

Setting that property and saving it requires opening the form in design view, whether done manually or programmatically, must be from design view.

so while I have the form open in run mode, I can vba open in design view make the change and save the form without messing up the current status of the active form?

I am missing something, when I try to set the new value getting an error
Dim newText As String
'"C:\Users\rbetz01\Documents\BSC-work\SMU-broker-adoption\Reports\"
Text27.SetFocus
newText = Text27.Text
DoCmd.OpenForm "email_track_rpt_request-form", acDesign
'Text27.SetFocus (get the error here)
Text27.DefaultValue = Chr$(34) & newText & Chr$(34) (get the error here)
DoCmd.Save

Don't need to set focus.
