Your question is unclear.
Do you want to show the amount of validations that have failed on input?if so You would need to use an onchange microflow that would change a validations count. this validations count be an attribute in another object thats associated. (this would require a relationship between the object you using and another object).
the associated object can then be placed on the right hand side..
remember you would need to also do an object refresh in the object microflow to show the updated validations count.
