I currently have an IF statement formula nested into a longer SWITCH formula, and am looking for a way to modify it some. Currently it is

IF({Total Order Sold Price} < 15, 2.95,
IF({Total Order Sold Price}>= 15, {Sold Price} * .2))

I want to first check for data in the {Total Order Sold Price} field. If there is data, I want it to run this set of IF statements. If there is no data, I want it to run the same IF statements, with a slight modification:

I’ve tried writing it a few different ways, the best I came up with is this:

IF({Total Order Sold Price}, IF({Total Order Sold Price} < 15, 2.95, IF({Total Order Sold Price}>=15, {Sold Price} * .2))),
IF({Total Order Sold Price}=BLANK(), IF({Sold Price} < 15, 2.95, IF({Sold Price}>=15,{Sold Price} * .2)))

Nothing is working so far though. Any help is appreciated
