Hi,
I am trying to implement the Follow up on a message in teams flow. We would like to, besides the standard choices, ad a field where the user can type his own interval.
Now I need to create a flow that checks both variables and checks if the value provided in the tekst box can be used in de delay. So if the box is empty or zero and the user did not pick a value from the choice boxes it should return a message to the user that the value provided is wrong.
I have been trying al kinds of things but right know it looks like the condition that checks if the tekst box is empty. Regardles of the value provided the flow stops working and does not give any feedback to the user.
Does anybody have any idea why the condition is not working?
Hi @ScottShearer ,
Thanks you for you reply. I tried it using the empty expression 2 ways:
1. Empty('<Variable>') is equal to true
2. <variable> is equal to empty()
Unfortunatly it still does not work. At option one the condition still does not go the right path, it uses the if no statement and i get the following error: The property 'count' must be provided in the 'Wait' action 'interval' inputs.
When i use option 2 i get the following error:
Unable to process template language expressions for action 'Voorwaarde' at line '1' and column '6993': 'The template language function 'empty' expects one parameter: the object, array or string to test for emptiness. The function was invoked with '0' parameter(s). Please see https://aka.ms/logicexpressions#empty for usage details.'.
Any other thoughts?
Thank you again.
To check for an empty value try using the empty() expression. Let me know if you need an example.
