Open Data Kit how to get a substring in reverse order using "calculate="substr('Test',1,2)='e'""

I have a question regarding getting a variable length string in getting inputted in to the code and finally returns a sub string with X starting point and Y end point. X and Y are also two other variables.

I don't think there is an easy way to do this.
