Help counting number of runs of numbers (excluding zeros)

Hi there

I'm looking for a bit of help to count the number of runs of a number but not including runs of zeros.

I've scoured the internet but just can't see anything that ignores zeros.

Basically I have a column of data made up of 1's, -1's, and 0's.

I need to know the total number of runs or 1's and -1's but not the 0's.

Can any one help out with this?

Thanks
