Look Up Non-zero Value To Left Of Current Column

I need a formula that will look in an array and return the first non-zero value it finds to the left of the column where the formula is located. For example, in a row with the following values:

$12,000 $- $- $24,000 $- $-

I would like to place a formula below each cell (in the next row) that reviews the row above and returns the first non-zero value to the left of the location of the current cell so that the results look so:

$12,000 $12,000 $12,000 $24,000 $24,000 $24,000
