Hi @Nigel O'connell 

All fields from start form are available in the left side of the card, but there is an option to update phase fields based on start form fields.

First you should “duplicate” fields from the start form in the desired phase and then you have to create an automation considering "when the card enters a phase" so "uptade a field", using start form fields to update your phase fields.

​Please, let me know if I have answered your question.

Hi there Nigel! You can find the information of all the cards inside of the phase, but not of one specific card in a specific phase. To do the former: 

{
  phase(id:123456){
    cards{
      edges{
        node{
          title
          id
          fields{
            value
            name
          }
        }
      }
    }
  }
}

and to find the field value information of only 1 specific card: 

{
  card(id:123456789){
    fields{
      name
      value
    }
  }
}

Hope this helps!
