If you want to pass the value entered or selected in the controls, then you have to pass the control reference and not datacard. So the control names will be something like DataCardValueXXXXX and you can verify this by selecting the control inside datacard. Now, when you have control name for these, the expressions that you need to enter for different controls :
Text Input -> DataCardValueXXXXX.Text
Dropdown -> DataCardValueXXXXX.Selected.ColumnNametoSelect
Hope this Helps!
