And what exactly is "this error".  What is the response you get?  How are you doing the conversion?

The Result.Response variable is a string, that's why you get this error. The Float64() function expects a number.

If you want to get the entered "number of iterations" from the Message Popup step, better use the Val() function:


Locals.numberOfIterations = Val(RunState.Sequence.Main["Select number of iterations"].Result.Response)

Actually i found this function (float64()) in TestStand for loop example.

Where do i get the list of functions available in TestStand?
