CCL: Problem about geometry optimization - StepSize option



Dear all,
 
Initially, I performed Gaussian calculation by option such as lower part.
        # UB3LYP/STO-3G SCF (Conver = 4) Opt Freq Test
But, "Maximum Force" value was not converged, and I can't optain good result.
So, I have wanted to use the "StepSize" option, and performed calculation by following option.
        # UB3LYP/STO-3G SCF (Conver = 4) Opt(StepSize=5) Freq Test
By the way, syntax error happens continually. I can't find a reason why occured this error.
Do you  know about this problem? Help me, plz~!
 
Thank you for reading. 
 
Regards,
Kwanyong
