Integral won't converge to solution

I have an integral that won't converge to a solution for a specific set of variables (the solutions over a range of variables are sought). I've attached the whole worksheet and thus a lot in it isn't relevant to the solution so just skip to the bottom the find the error-riddled integral.

Thanks in advance to anyone taking the time to help out.

Ok.  It's a numerical sizing problem.  The solution, strange though it may seem, is simply to put the 2/E term inside the integral!!

See attached.

You need to upload the .txt file input at the start as well or the rest of the file won't calculate.

Opps, sorry. Changed the worksheet so the txt isn't needed.

Because you are passing an range variable to the integral. Firstly pass a integer to the integral and change the IF statements to integers.
