After filling the sample form IEQp1 table IEQp1-4 and press calculate I get a Y (yes) in both compliance with IEQ prerequisite 1 and credit 2. However, the cell below which links to IEQc2 sample form still shows a N (No). I have filled the mechanical ventilation section with all the AHUs and rooms. Also the table IEQp1-A4 shows compliance with prerequisite and credit 2.

Could anyone advise on what could be the problem for not having the linked cell properly changed to Y (Yes)?
