Hi mahesh, I followed your guide but when I run

> contractInstance = VotingContract.at(deployedContract.address)

I get

Error: Error: VM Exception while executing eth_call: invalid opcode

Which version of `ethereumjs-testrpc` are you running?

Any ideas on what I could be doing wrong? I followed your instructions very closely.
