How can I assign the Repeat steps Iteration output to an input?  
Iteration is an Output parameter:

But Assign Output is disabled on child:

The Outputs have to share the same types as the Input. For Repeat Iteration that is a string. You could use something like Log Message, but you won’t be able to pass that to Delay, since that input is a Double:

Its a string? Didn’t expect that… Is there an easy way to findout an output’s or input’s type?

Yeah it’s a string because you get the entire “N of M”. There really isn’t a good way to identify the types in the UI today, but it is stored in the Test Plan.
