The court below has judiciously unraveled this complex post-dissolution proceeding. However, the determination of the amount of appellant’s alimony obligation for the 1974-75 accounting period appears to have been based upon some erroneous computations. In order to determine the *621amount of alimony payments required by the property settlement formula, the court projected appellant’s income for the first one-third of the accounting period. In making these calculations .it now appears that the court should have used $3,114.78 in lieu of $7,114.78 for cash draws and $680 in lieu of $2,040 for the auto lease payments. Had the court used these figures, appellant’s alimony obligation for the 1974-75 accounting period would have been $314.34 per month rather than $559.78 per month. The order is hereby amended to reflect this change, and the arrearage is reduced to that extent.

The order is affirmed as amended.
