End of Expression error message during UIPath Academy String lesson

Learning Hub Academy Feedback

I am completing the String section of the UIPath academy. I am trying to follow along with the video, but keep getting error messages. As far as I can tell, I have done everything exactly as has happened in the video, but I still get the errors (this has happened on a couple I’ve done so far).

It is the lesson on strings, and I have error messages in 3 of 4 assign activities (I’ve posted the expressions below). I’m obviously doing something wrong so hoping someone can point me in the right direction.

message.Split("."c)First.ToString.Substring(message.LastIndexOf(“author”))

message.Split(“.“c)(1).ToString(”:“c)Last.ToString.Split(”,c”)ToList

String.Format(“Availability for {0}: {1}”,author, StringJoin(“;” +vBCr,bookstores))

Hi @chickey,

Welcome to UiPath Community!
Can you attach the xaml file so that we can see what is the error you are getting & rectify it.

Welcome to our community

  1. .first and . last in your string there dot(.) Is missing
  2. in the second string manipulation in splits method c in between double quotes

And also check messages variable .it should be string nor generic
And one thing notes that variable where you store this string after manipulation
