Help with IIIF Statement

[CDIns]

I have three blank columns, 1,2 &3. 

I am doing a Join tool to populate columns 1 & 2. If both of these columns come back as "NONE", I'd like to have column 3 populated with "OK". If either column 1 or 2 has something other than "NONE", I'd like column 3 to populate as "No"

Currently I have as follows:

IIF(([Column1]="NONE" AND [column2]="NONE"),"OK",[Column3])

This is working for the first part of my condition but leaves the field blank or null for the records that do have something other than "NONE" in column 1 or 2. 

Can somebody please help me finished my IIF statement? 

Thank you,

Try this in the formula tool 

If [Column1]="NONE" AND [column2]="NONE" then "OK" else "No" endif

@CDIns - just change [Column3] to "No" in your expression

Thank you! Is there any good resources on here for me to kind of understand how excel formulas such as IFs or SUMIFS are written in Alteryx?

@CDIns have you tried this https://help.alteryx.com/current/en/designer/functions/conditional-functions.html  ?

Also if these work please mark them as a solution (you can mark more than one as a solution)
