'if' Statement Arguments Error

RymaAneliunas1 — Mon, 08 Jan 2018 15:39:04 GMT

Hi, I have a conditional statement calculation in my survey in that is returning an error:

"XPath evaluation: cannot handle function 'if' requires 3 arguments, Only 2 provided."

As you can see I have four, so I am stumped. Your input is much appreciated.

if(${stoff}>1200,'EXT INFLUENCE',if(${stoff}>860,'PROTECTED',if(${stoff}>840,'MARGINAL',if(${stoff}<840,'UNPROTECTED'))))

Hi Ryma,

Your innermost if statement will need a value if false (that's the 3rd value the error mentions). It looks like the evaluation can be simplified to 3 if statements:

if(${stoff}>1200,'EXT INFLUENCE',if(${stoff}>860,'PROTECTED',if(${stoff}>840,'MARGINAL','UNPROTECTED')))
