Dynamic content from Common Data Service is returning Null

[bhitchlockfcs]

I have a strange issue I cannot figure out.

I have a flow which when triggered should retrieve one record and then create a related record with values being a percentage of the source records. Seems straightforward, however the Flow fails on the create record step with the following error: 

Unable to process template language expressions in action 'Create_PC_Line_Based_on_QS' inputs at line '1' and column '2726': 'The template language function 'mul' expects its first parameter to be an integer or a decimal number. The provided value is of type 'Null'. 

The Expression referred to is a simple multiplication statement: 
mul(body('Get_the_QS_Coverage')?['ssru_blanketlimit'],variables('QSPct'))

When I look at the output from the 'Get_the_QS_Coverage' action I see all of the values in the output:

To test I tried initializing variables with the field values but same issue arises no actual values are returned from the get record action.

I'm stumped. Can someone help me figure this out?

Hi @bhitchlockfcs 

Could you post your retrieve flow step screenshot please?

Thanks

Sure, @abm  the retrieve step is below. Followed by the results.

Hi @bhitchlockfcs 

Try this

mul(body('Get_the_QS_Coverage')?['value']?['ssru_blanketlimit'],variables('QSPct'))

Let me know the result.

Thanks @abm, tried that sadly just got another error:

Unable to process template language expressions in action 'Initialize_Building_Limit' inputs at line '1' and column '2726': 'The template language expression 'mul(body('Get_the_QS_Coverage')?['value']?['ssru_blanketlimit'],variables('QSPct'))' cannot be evaluated because property 'ssru_blanketlimit' cannot be selected. Array elements can only be selected using an integer index. Please see https://aka.ms/logicexpressions for usage details.'.

Hi @bhitchlockfcs 

Thanks for your quick reply.

Please try this expression.

mul(body('Get_the_QS_Coverage')?['value']?[0]?['ssru_blanketlimit'],variables('QSPct'))

Thanks @abm  that worked!

Any idea why the body fields need to be formatted that way? I have several more values to use in my flow and it appears I have to type the body expression for each value.

Hi @bhitchlockfcs 

That's great.

The value is an array collection. Please see your earlier screenshot you provided.

Thanks
