Hi @Harry_G,

I have made a test on my side, please refer to screenshot below to create the flow:

The expression in the Compose 2 as below:

substring(outputs('Compose'),6,22)

And you could also enter the expression below in the Compose 2:

last(split(outputs('Compose'),'[113] '))

The flow would run successfully as below:

Best regards,

Thank you but you have manually mentioned the 6 and 22 as number for index and characters . How to get it automatically or in other words what if we aren't sure about what those numbers could be?
