I have a solution where I am using a SharePoint list as the source for a combobox to lookup values in a form. The SharePoint lookup list has multiple columns, one being a department and another being an email address. When the user selects a specific department from the combobox, the email address associated with that department is added to an adjacent field and a notice gets sent to that email when the request is submitted. Initial submission works fine.
The problem I am having is that when I try to set the default value of the combobox control to "Parent.Default", I get an error that it is expecting a table. I am not sure what to do in order to make this work. I tried enclosing Parent.Default in square brackets and in another instance tried enclosing ThisItem.'Division / Department' in square brackets. This gets rid of the error, but then the value doesn't always show up in the form after submission.
How can I ensure that the value stored in the single line of text field from the combobox is displayed as the default when the form is opened after submission?
Thanks in advance for any help!
