i) action="installworld"; flag_count=$((flag_count+1));;

But when tested it just put 1 into flag_count. it is not adding one to 
the value all ready in  flag_count.

Stilling missing the point here
I want to perform math here. if more than one flag is coded them I want 
the count to increase by 1 for each flag on the command, not change the 
contents of the count to 1.

Again take note this is .sh shell type.
