Union Expression wont allow me to copy the collection one phase into the collection two phase

[KeeganClarke]

Hi Power Community,

I am trying to get unique values so am applying the union expression however when inputting the expression it goes straight into my file not giving me the opportunity to input the second collection phase.

I'm assuming I may be missing a step and may need to do something before this phase?

Hello @KeeganClarke ,

the expression editor has its flaws, the best approach would be to build the expression in some text editor and then paste it in the expression editor:

• use the array for the unique values in some action
• copy it from the action into text editor
• build the expression - union(array, array)
• copy/paste the whole expression in the expression editor and use it in your flow

Thanks Tom, thats one way around it!
