I don't write pure bash and I don't think we have seen your code to populate the array. Might be worth posting that script.
Remember that array elements are numbered from zero. In your case zero to six (i.e. seven elements).
Here's a bit of test code to get you started on how to walk the array and how to refer to the elements in shell script. You will need to change variable names to match the rest of your script and maybe change "echo" to "printf" depending on what you have been taught.

The idea is to build your script in simple stages and test each stage.
Once you can read back you array of the seven numbers the user typed you are in a position to insert code to do more (like find the highest value). Finding the median will be interesting.

Code:
echo "Read back test array in the same order it was created"
counter=0
counter_max=6
while [ ${counter} -le ${counter_max} ]
do
        echo "Array element ${counter} = ${num_array[${counter}]}"
        counter=$((counter+1))
done

local(n)							    [incr Tcl]								  local(n)

__________________________________________________________________________________________________________________________________________________

NAME
local - create an object local to a procedure SYNOPSIS
itcl::local className objName ?arg arg ...? _________________________________________________________________ DESCRIPTION
The local command creates an [incr Tcl] object that is local to the current call frame. When the call frame goes away, the object is auto- matically deleted. This command is useful for creating objects that are local to a procedure. As a side effect, this command creates a variable named "itcl-local-xxx", where xxx is the name of the object that is created. This vari- able detects when the call frame is destroyed and automatically deletes the associated object. EXAMPLE
In the following example, a simple "counter" object is used within the procedure "test". The counter is created as a local object, so it is automatically deleted each time the procedure exits. The puts statements included in the constructor/destructor show the object coming and going as the procedure is called. itcl::class counter { private variable count 0 constructor {} { puts "created: $this" } destructor { puts "deleted: $this" } method bump {{by 1}} { incr count $by } method get {} { return $count } } proc test {val} { local counter x for {set i 0} {$i < $val} {incr i} { x bump } return [x get] } set result [test 5] puts "test: $result" set result [test 10] puts "test: $result" puts "objects: [itcl::find objects *]" KEYWORDS
class, object, procedure itcl local(n)
