Invalid arithmetic operator on string concatenation

Hello.

Code:

LEAP_VERSION="4.2"
export ARRAY_MAIN_REPO_LEAP=('zypper_local' 'openSUSE-Leap-'"$LEAP_VERSION"'-Non-Oss'  'openSUSE-Leap-'"$LEAP_VERSION"'-Oss'  'openSUSE-Leap-'"$LEAP_VERSION"'-Update'  'openSUSE-Leap-'"$LEAP_VERSION"'-Update-Non-Oss')

Seems that the - is interpreted as a numeric operation when next to $VAR

The error is :

Quote:

bash: 4.2: syntax error: invalid arithmetic operator (error token is ".2")

I was expecting this result :

Quote:

zypper_local openSUSE-Leap-4.2-Non-Oss openSUSE-Leap-4.2-Oss openSUSE-Leap-4.2-Update openSUSE-Leap-4.2-Update-Non-Oss

I am using bash : 4.3-79.15
Any help is welcome.

NAME

       Nagios - network/systems status monitoring daemon

SYNOPSIS

       nagios [-h] [-v] [-s] [-d] <main_config_file>

DESCRIPTION

       nagios  is a daemon program that monitors the status of various network accessible systems, devices, and more. For more information, please
       consult the online documentation available at http://www.nagios.org, or on your nagios server's web page.

OPTIONS

       main_config_file
	      The main configuration file.  On openSUSE systems this defaults to /etc/nagios/nagios.cfg

       -h     A helpful usage message

       -v     Reads all data in the configuration files and performs a basic verification/sanity check.  Always make sure you verify  your  config
	      data before (re)starting Nagios. You can also use the Nagios init script to verify your configuration - try: rcnagios check_verbose

       -s     Shows projected/recommended check scheduling information based on the current data in the configuration files.

       -d     Starts Nagios in daemon mode (instead of as a foreground process).

FILES

       /etc/nagios
	      Default configuration directory for nagios
