Percent complete Revenue generating incorrectly

Percent Complete Least (999999999999.00 ,(( 0. * (382464.00 - -110404.00)) - 492868.00 ))

110,404 = Burdened cost amount on the Estimated Cost Budget.

This  is a random revenue error, the negative 110,404 is pulling from the Burdened column instead it the Zero value entered in the Raw Cost Column.  All other tasks created the correct revenue except for the one with zero cost values.

Any help would be appreciated.

thank you
