To the best of my understanding, this is not available in Ms. Access. It may be part of an excell library which could be included in Ms. Access, however you would need to have a FULL undestanding of the function to apply it.
I would suggest that you instantiate the resolver function in an Excel worksheet, with all of the Arguments as NAMED RANGES. Then, you could export each data set from Ms. Access to the appropiate named range, recalc the sheet and read in the value(s) from the calculation.
