If then script using greater than and less than

I have a form called Recruitment, and in that form I have the following fields:
 
Target (number field)
Current Recruitment Total (number field)
Local % (formula field)
Range (dropdown field)
 
Local % calculates Current Recruitment Total/Target * 100
 
What I want to do is create a report that will have Range on the x-axis  and count of Local % on the y-axis.  The reason for this is that when I currently create a report, it automatically generates the x-axis for me, and I do not want that.  I want my x- axis to have the following ranges:
 
no recruitment
1 - 40
41 - 80
81 - 90
91 - 100
+ 100
 
So I created Range so that I could drag this in the Report generator and hopefully get the intended results.  That part should work fine, however, I would like to add a script for the On Success for both Form On Add and Form On Add so that I do not have to manually do this each time. 
 
I did the first bit of the code ok:
 
if (input.Local = 0)
Range = "no recruitment"
 
That bit works, however, I cannot seem to get the code right for the following bit:
 
if (input.Local >=1 and <=40)
Range = "1 - 40%"
 
I know the main issue has to do with the use of "AND" but as a novice, I really do not know how else I can script this.......
 
I have tried the script using "concat" but refused to work and I have up.
