Help fixing my database script

1. The problem statement, all variables and given/known data:
I need help I get a variant of syntax errors when compiling my script to maintain a database. It's a simple database meant to create/view/maintain vehicles.

2. Relevant commands, code, scripts, algorithms:
my if statements have many syntax errors and I'm lost as to why. One key lines is line 8 my first if statement. Thanks in advance.

3. The attempts at a solution (include all code and scripts):

Code:

#! /bin/bash
# Automobile database

db=arg1
command=arg2
case $db in
    #create:
if [ -f "$db" ]; then
echo "DATABASE EXSISTS"

 if [ $arg3 != "" ]
 echo $arg3 > db

else
echo "Automobile Database" > db
echo "New database created"
fi
  esac

#add

read -p "Make of the car: " make

read -p "Model of the car: " model

read -p "Year of the car: " year

read -p "Color of the car: " color


if $year < 1870 || $year > 2020
echo "Error with $year"
fi
echo "$make, $model, $year, $color" >> db
echo "Successfully added a record to the database"

case $arg3:
 max=$( wc -l db )
 #all:
 cat db

 if $arg4 > $max
 echo "Error"
 fi
 sed -ne "1p;arg4p" db

#range:
if $arg4 > $max || $arg5 > $max || $arg4 > $arg5
error
fi
sed -ne "1p;arg4,arg5p" $db
esac



#delete:
        case $arg3:
        max=$( wc -l db )
      sed -ie '2,$d' db
     single:
     if $arg4 > $max
     echo "error"
     fi

     sed -ie "$arg4d" db


     range:
     if $arg4 > $max || $arg5 > $max || $arg4 > $arg5
           echo "Error"
           fi
     sed -ie "arg4,arg5d" db
esac

rpccp_remove_entry

remove entry(1m)														  remove entry(1m)

NAME

       remove entry - Removes a name service entry from the name service database

SYNOPSIS

       rpccp remove entry  entry-name [-s syntax]

OPTIONS

       Indicates  the  name  syntax of the entry name (optional). The only value for this option is the dce name syntax, which is the default name
       syntax. Until an alternative name syntax becomes available, specifying the -s option is unnecessary.

ARGUMENTS

       Indicates the name of the target name service entry.  For an entry in the local cell, you can omit the cell name and specify only the cell-
       relative name.

DESCRIPTION

       The remove entry command removes an entry from the name service database. The name of the entry is required.

   Privilege Required
       You  need read permission to the CDS object entry (the target name service entry).  You also need delete permission to the CDS object entry
       or to the parent directory.

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLES

       The following commands run RPCCP and remove the entry /.:/LandS/anthro/Cal_host_2 from the local cell of the name service database: $ rpccp
       rpccp> remove entry  /.:/LandS/anthro/Cal_host_2
