Length function returning incorrect value

[JamesMoyle]

Hi All

I've been bashing my head against the wall trying to figure out why a length function was failing to pick up the variables with a particular number of characters. I decided to test it in a much more basic flow as below

Now I've got all my fingers and thumbs, so I didn't need to take my socks off for this one, and that looks like eight to me. So why is the result 10 (below)?? I'm pretty new to this, so I am sure that this is worth a few eye rolls 🙂

It is returning the correct value. You are getting the length of the static string Get_DTENDa which is exactly 10 chaacters. You need to use length(variables('Get_DTENDa')) - that should return the value you expect.

Hey @JamesMoyle 

Editing my Answer as @Paulie78 saw something I and you missed 🙂

You formula should be - 

length(variables('CheckLEnght'))

Please mark @Paulie78 Correct.

That makes sense - but now it is saying 

The inputs of workflow run action 'Compose' of type 'Compose' are not valid. The variable 'Get_DTENDa' must be initialized before it can be used inside action 'Compose'.

Didn't I initialize the variable in the previous action?

My error, the variable name you created is called Date.

Thank you - this has created even more questions for me, but you have more than generous already and this has been really helpful to understand the logic of what's going on!
