Grab part of outlook subject with Flow Expression

[StephenM]

I am building a Flow with Outlook as the trigger - i need to grab the subject and remove part of it. 

the email subject will be somehting like "SM Trigger :123" and it will always start with "SM Trigger:". I need to use the bit after (in this case 123) as the file name to save it.

any help on how to grab just the bit after the ":" (e.g. 123) would be much appreciated

I'm thinking either a last(split(  or replace( but i cant quite figure it out.

thanks

Stephen

Hi @StephenM,

Please take the following flow configuration for a reference.

I used actions initialize variable and Set variable in the flow.

The function used in the Compose action is:

split(triggerBody()?['Subject'],':')

The function used in the Set variable action is:

outputs('Compose')?[1]

When a new email with the subject “SM Trigger: test123”arrives, the flow works fine and it returns “test123” after the “:”, please check the following screenshot:
