Peak Finder / Bandpass Filter errors on SimElectrical

I am having an issue with two blocks on SimElectrical:

1) From a simple sine wave input, how do I increase samples per channel to above 3 such that I can use the Peak Finder block?

2) My bandpass filter (attached to my sine wave output) is giving me an error as follows: Output port 1 of 'Circuit/Bandpass Filter' is a one dimensional vector with 1 elements.'

Any help would be appreciated,
