string function to get selective text from long string

I haven't used the string function since old days of Lotus but seem to remember that I can find a special character ($), move right until reaching a blank space, then copy those characters between special and blank and copy to a cell. Then continue to find same special character again, same process and copy to cell in row below. Specifically here I am trying to get the dollar amounts from this string, put them in rows to add up.

Thanks,

It is but for the current activity before next statement there is no pc download. Also, I would like to know how to do this to manipulate other data in our office. Thanks
