[plug] problem found in "if" statement

[Jon Miller]

I've found a problem in an "if" statement and cannot find a fix.  The statement is
if [ "$vMLSTAT" >= 0 ]; then
  .....
  .....

fi
 I'm getting a unary operator expected.  I've tried also the following and got a error message stating that [ : : integer expression expected
if [ "$vMLSTAT" -lt 0 ]; then
   ......
   ......
fi

Any ideas would be appreciated.

Thanks
