adding a tolerance to DWVlookup

I am writing rules inside DriveWorksSolo to better/automate my company's print/model creation.

I'm using excel spreadsheets that contain our tooling lists, (Punch&Die sizes, other tooling sizes, etc...)

Curious if there is a way to add a tolerance to a DWVLookup rule,

Example: I'm using a combo box, with a rule stated as follows:

DWVLookup((SealØReturn+.016) - (OuterCaseMetalGaugeReturn*2), DwLookupRoolFormList, 1, 1, TRUE)

I was curious if there's a way to add a tolerance to the search, to look for the size tool needed, with a ±.005" tolerance?

I've tried some things, but have had no success. It may be very easy, and I may be over thinking it. haha

Any input on this would be appreciated, as I am not 100% familiar with rules/commands yet. Still in the learning process
