Access and Change Dropdown Value

Access and Change Dropdown Value

Hi all,

I'm creating a simple leads management app, but now had a problem with dropdown.

In Add leads I have lookup value to "Leads category" which is a single line that showed up in "Add Leads" form as a dropdown. In "Leads category" there are some category like "Call In", "Follow Up", "Booking", "Paid". I want to set default leads category for each new leads as "Call In" but I got an error when submitting form because of different data type. Here is my code

input.Leads_Status = "Call In";
