Using Switch Formula but adding an exception

Question

&nbsp;Hi There,&nbsp;I have the below formula that works fine &amp; calculates correctly.&nbsp;&nbsp;=SWITCH(W401=Z$2,TRUE,S401*0.1,FALSE,S401*0.025,)&nbsp;I would like to add an exception to only perform this calculation if 3 different cells do not contain certain words from the same line (these words all change as come in from a different tab based on account information, the exception is only needed on one combination) , is this possible? Ideally I would like to do this all in the same cell IE add it to the above formula.&nbsp;&nbsp;&nbsp;Many Thanks&nbsp;&nbsp;Jim&nbsp;&nbsp;&nbsp;&nbsp;
