The Problem

Question mark (?) appears in Markup field in the Price Codes file.

The Solution

This indicates that there is an error in your formula and therefore the markup cannot be calculated.

Check the price sampler column on the right. If it too shows question marks after clicking on the Reset UI button, then the formula has an error in it.

Take a look at the equation in the formula field or contact tech support 1-888-281-3303 for assistance.
