Hi @LokeshCapita ,


Could you show how you are using the IsBlank function to evaluate if the Organization field is empty? Depending on how the data is structured it could be something as simple as this:




The documentation for this function can be found in more detail here.



Let me know if this answer helped you move forward!




Hi @rimatos 

thisis how i am using



Hi @LokeshCapita ,


I've made a slight change to the function you provided me in the previous reply.


Could you try it now on your side? If it still fails could you show me a print of the error that you get?







hi @rimatos 

this is my full code

'ConfirmLatePaymentPerfomBoundAction'.Run(ModelDrivenFormIntegration.Item.'Late Payment');Navigate(ConfirmManualMatch_Success,Transition.None))


when i am tring this its going only to error screen even though my organisation field is not blank .its not  executing performbound action

Hi @LokeshCapita ,


So the way the IsBlank function works is it tests for a blank value or an empty string. The test includes empty strings since some data sources and controls use an empty string when there is no value present. My suggestion would be to try and test specifically for a blank value using if( Value = Blank(), ... instead of IsBlank.


Another function you could try is the  IsEmpty function, which tests whether a table contains any records, and in this situation could also help to unblock you.


You can consult on both these functions here:




Hope this helps you move forward!


If you are still struggling after attempting these workarounds, I would suggest raising a ticket with Microsoft Support from your admin portal:
