Time difference measure by one column

[odzelashvili1]

Hello PBI community 🙂

My table has this view:

I want to see what is difference between VISIT_CREATE and VISIT_END.

For this task, I'm using DATEDIFF function, which really works:

Now, I want to see total average time difference for all visits in one visual, but, when I put my measure into card, PBI gives me wrong result.

In my table screen, visit_key 1 time difference is 24s, for 2 - 2,126s and average must be 1,075s, but my measure says it is 2,126s 😞 

Have any idea how to solve this task?

Thanks in advance!

@odzelashvili1 , Try a measure like

AverageX(Values(MainTable[Visit ID]), [WD_create_to_end])

I have one very stupid question, 

when I'm using code like this:

and then this:

it works, but it does not work when I'm using this code:

Can anyone tell me, what's wrong with second code?

thanks 🙂
