Grid question - hide a row based on a previous answer

Hello,

I have 3 questions that depend on previous answers as it follows:

1st question (numeric): Quantity of events attended.

2nd question (free format): Detail of the events attended (max 5 and it shows the lines based on the previous question). Image 1

3rd question (grid): Rate some attributes, where I need the following:

1. I need to get a random event between the detailed ones in the 2nd question and get the name, year and place that the user input to that event. This to fill the question "Pensando en el concierto/festival (name of the event) that you went on (year) in (place)...". For this question, the name of the variables are as it follows, where 1 changes is the number of the row:

   1. Name - DetalleEventosPasados_nombre1

   2. Year - DetalleEventosPasados_fecha1

   3. Place -DetalleEventosPasados_lugar1

   4. Know the cost - DetalleEventosPasados_boletoconocimiento1

2. For that same event, I need to evaluate if they answered Yes or No in ¿Sabes cuanto costó cada boleto?. In case they answered No, I need to hide "Precio" (Price) row in the grid.

3. I need to add the column "I didn't use it" in the grid, but this only applies to 2 rows: "Estacionamiento" (Parking) and "Calidad de comida/bebida" (F&B Quality).
