Not so obviously, but I will say the obvious again ... " error = > amount of transaction has an incorrect signal to the given transaction action ".
Can't help you much, do you still with this mechi interface, but I believe that this message is actually quite explanatory. I believe it is a problem of signal (+/-). See law, tries to change the signal and see if not the error.
