I asked this question before: When I choose a Value from a drop-down list in Team Forms can that value populate the value its connected with dynamically example I choose business name and it populate the address. the answer i got from help and i got from Anthony help me figure this out. Now i have a question as to if it is possible to somehow manually input values in the same field.
Hi Sky,
The best way to do this is by enabling the "Allow Manual Override of Calculated Value" option.
However, with that said, there is currently an issue with that feature which may force you to use a more complex work around which has been described in this link
