Sum of positive values in vector and sum of negative values in a vector

I have created a vector that has both positive and negative values.

I would like to sum all the positive values, return the number, and then separately sum the negative numbers and return the number.

Is this possible?

Thanks,

Ross

Apart from that, how about this...

Attached is a Prime 4 file, with the advice from @Werner_E (see below).
