Sqoop job table parameter issue

Hi ,
Below shell script is not running giving error like
Missing argument for option: table

mytable= echo “customer_11”
echo $mytable
sqoop import --connect jdbc:mysql://ip-172-31-13-154:3306/retail_db --username sqoopuser --password NHkkP876rp --table $mytable–check-colu
mn mytime --incremental append --last-value ‘$lastv’ 2>&1| tee -a mysqoop.log

Can anyone tell me wht -last-value is taking dynamic parameter but not --table

I am just considering first 2 lines I am not expert is bash scripting
but
mytable= echo “customer_11”
echo $mytable

$mytable has no value in it hence hte sqoop command cannot work…
sorry if I am wrong
