Hi, 

I created a flow to calculate test results and send email based on the pass or fail condition. When I run the flow I get the following error message at the condition.

I have this expression at the condition -

float(outputs('Get_a_row')?['Body/Score'])
 
Please know that I dont have a coding or programming background but was tasked to created this flow for an internal quiz that we are supposed to roll out to a larger audience. Can you please help correct this error? 
Appreciate your help!

    Insert a compose just before the condition and add the outputs('Get_a_row')?['Body/Score'] to it.  That way you will be able to see the value that you are trying to convert to a float.  It needs to be a string that contains a number.  Otherwise you will get the error you are seeing.

    Can you help me with compose? I dont think I follow how to add it before the condition..

    Just click on the plus inline right above the Condition action.  Then add a 'Compose' action.  Insert the same dynamic content field in the Compose that is in the left side of the Condition.

    If the Condition is the first thing inside a loop then you won't have a plus above the Condition.  In that case add it just after the Condition and then Drag and Drop the Condition below the Compose after its added.

    Ahh it made sense! So did exactly what you told me to, but I still get the same error and warning at the condition. It passes the compose action just fine. Here is the screenshot...

    Hey everone! I still need help with this error. I learned that no matter what the condition is (float, outputs, isfloat), I get the same error. I dont think the cause of the problem is at the condition level but I could be wrong..

    Use that Compose to see what the value is that you are running the condition on.  That should help you figure out why it can't be converted to a float.

    Hi Pstork1, 

    I tried the compose multiple times. The flow passes the compose just fine but then throws the same error at the Condition for Float(outputs('Get_a_row')?['Body/Score'])

    I get that it passes the compose.  The point is to use that in the run log to see what value is being passed  for outputs(Get_a_row')?['Body/Score']) so that you can determine why it won't work with float().  I suspect there is something like the number being text or an integer that is causing the problem.  On the run where you get the error what is the actual value in the compose for that output?

    I have the flow attached to a spreadsheet to calculate score. Do you think I need to make any changes to the cells of the spreadsheet?

    Thank you for helping me out with this issue. I was able to rectify it. I have another unrelated question. In order for me to integrate a quiz with power automate, do I always need to be the owner of the quiz?
