Hi guys. 

I am using For Each to display each item using dict.values. The problem is I can't get key by value of the item in dictionary.  

Please suggest any ideas.

I think you forgot to initialize the dictionary, which is mandatory to add values to it and also to fetch values from it. Use Assign activity to initialize the dictionary.

Hi Slava, I think you are facing this issue because you didn't initialized the dictionary. When you insert AddToDictionary activity to the sequence and create a dictionary variable you have to initialize it with newDictionary() method. You can initialize a dictionary in 2 ways:

1. Use Assign activity to assign dict variable to newDictionary(key_variable_type, value_variable_type):

  dict = newDictionary(Of String, String)

2. Initialize the dictionary while creating the variable by providing default value as newDictionary(Of String, String)
