Avoid "++ requires lvalue" Error in Loop Calculation

Hi All,

Please help me to perform sum of values in a loop, I am getting following error:

"total=0++432907765772: ++ requires lvalue"

where actual statement is as : total=$total+$amt

where amt can have +ve or -ve values

Thanks

NAME
amt - run abstract machine test SYNOPSIS
amt [-s] DESCRIPTION
The amt command is for use in a Common Criteria security certified system. The command is used to verify that the low level functions nec- essary to enforce the object reuse requirements of the Controlled Access Protection Profile are working correctly. /usr/bin/amt is a shell script that executes tests specific to your system. For a 32-bit system, the tests run as a 32-bit application. For a 64-bit system, the tests run twice; once as a 32-bit application and once as a 64-bit application. amt lists test results with a pass or fail for each test it performs, unless output is suppressed with the -s option. OPTIONS
The following option is supported: -s Suppresses output. EXIT STATUS
The following error values are returned: 0 All tests passed. >0 Count of the number of tests that failed. <0 Incorrect command line argument. ATTRIBUTES
