* Dear VMD users/experts, *
* I have been trying to use the Force field toolkit in VMD 1.9.2 Beta
(Windows) to parameterize a new molecule. **In the "Opt.Bonded" tab, when I
tried to Run Optimisation, I got the ** I got the following error message: *

*"can't use empty string as operand of "*"can't use empty string as operand

solution offer from there:
it didn't help me. Is there any way to solve this problem? *
