create a variable

[Pinoq]

Hey , I would like to know that how can I create a variable in order to store emails in a variable?

I have created a flow when trigger by when an item is created, send an email to assign to and CC email.

which CC email is a multiple selection of groups of email. It cause in some case if 2 persons selected in cc, assign to will receive 2 identical emails. Thus,I would like to to store all cc emails in a variable. How can I set it up?Because I cannot choose the variable in dynamic.

Hi @Pinoq 

Try to use the array variables and append the values to the array variable and finally use the join condition to join all the values in an array with ';' separated and then the final output to the mail CC. Try to use the below expression for joining the arrary variable.

join(variables('ArrayVariableName'),';')

Hope it helps, please like it or mark it as a solution if it resolves ur clarification or issue

Hi @Pinoq 

Based on your screenshot below please follow the below steps

1. In your 'Initialize Variable' section, create a variable of type 'Array' and in the value just give '[]'

2. In your 'Apply to each 2' action, remove the 'Set Variable' action use 'Append to array variable' and then use the above declared variable.

3. In the email action use the dynamic expression 'join(variables('array variable name'),';')'.

Hope it helps, please like it or mark it as a solution if it resolves ur clarification or issue
