How to embed expression inside another expression

[Dastan_Kodli]

@jinivthakkar @Hardesh15 @Gopala_Krishna 

Can anyone please help me to find out how we can embed expression inside another expression in ms flow

for e.g. Expression as follow: outputs('Get_a_row')?outputs('Compose')

where compose output contains key name of the 'Get a row' action of CDS connector.

I have tried concatenation but it is giving output as string concatenated value and not evaluating as expression

Expression for concat:- concat(outputs('Get_a_row'), outputs('Compose'))

Any help will be appreciated.

Thanks!

@Dastan_Kodli please can you let me know what are you trying to do as in logic ?

You're so close! You just need to put the second outputs in square brackets. So normally you'd do outputs('action')?['key'], with your expression you just do outputs('Get_a_Row')?[outputs('Compose')]

And then in your Compose just put accountid without brackets or apostrophes.
