Nested IF statement

[edcdcpowerbi]

I am needing to add a third if statement below, which replaces blank values with a 0. 

On its own it works fine, the other two if statements work without this third being added. 

How do i correctly insert this Third IF statement, as it stands i get a semantic error saying 'Too many arguments passed, 3 is the maximum'

RETURN
IF(
ISBLANK( SliderValue ),0, SliderValue,
IF( SliderValue > 0, ProjRR,
IF(SliderValue = 0, Actual)
)
)

Hello there @edcdcpowerbi , you already have three arguments in the highlighted part of your code. Therefore, all your arguments after it are causing the error. I think you can remove the "SliderValue" argument, or use a SWITCH() function instead of nested IFs() since it behaves almost like an IF THEN ELSE.

RETURN
IF(
ISBLANK( SliderValue ),0, SliderValue,
IF( SliderValue > 0, ProjRR,
IF(SliderValue = 0, Actual)
)
)

Hope this answer solves your problem! If you need any additional help please tag me in your reply.

Thanks for the help @goncalogeraldes. i did try to remove SliderValue, but to no avail. 

I did try the switch statement but it return True, instead of the values i wanted, where have i gone wrong? 

SWITCH(SliderValue,
IF(ISBLANK(SliderValue),0,SliderValue),
SliderValue = 0, Actual,
SliderValue>0,ProjRR
)

@edcdcpowerbitry this! 

SWITCH(
TRUE(),
ISBLANK(SliderValue),0,
SliderValue = 0, Actual,
SliderValue > 0,ProjRR,
SliderValue
)

@goncalogeraldes it still displays (Blank) instead of zero im afraid

[goncalogeraldes]

@edcdcpowerbi please send the full formula then. What is the SliderValue?

[edcdcpowerbi]

sure, here it is @goncalogeraldes 

VAR Actual = [Recycling Rate (PET)]
VAR AverageR = [Median Recycling Rate (PET)]
VAR SliderValue = [PETRecyclingRateOverride Value]
VAR ProjRR =
IF( SliderValue > 0, DIVIDE( SliderValue, 100, 0 ), Actual ) //var AverageRR = IF (SliderValue > 0, DIVIDE(SliderValue,100,0), AverageR)
RETURN
//IF ( SELECTEDVALUE (Jurisdiction[DRS Status]) = "Existing DRS" , ProjRR, AverageRR)

SWITCH(
TRUE(),
ISBLANK(SliderValue),0,
SliderValue = 0, Actual,
SliderValue > 0,ProjRR,
SliderValue
)

The way DAX handles BLANKS can be somewhat confusing so in this case it can be something related to DAX never considering the value to be blank and evaluating it as FALSE everytime. A possible workaround can be:

SWITCH(
TRUE(),
SliderValue = BLANK(), 0,
SliderValue = 0, Actual,
SliderValue > 0, ProjRR,
SliderValue
)
