Relevant in ODF form /xlform

how to display a question if the following conditions are met:
if Q1 the age varies from 18 to 36 years and that Q3= modality 2, 3, 4 and Q6= modality 4 and Q9= modality 2. if these conditions are met the question Q12 is displayed.

Thank you

You have to add logic to relevant column in that question you want to show/hide. If you have multiple conditions like in your case you can join them using Boolean operators
