If/Else Navigation

Posted on by Blizzardly

Hi all -

Working on a Power App writing back to Dataverse. I'm using an "If" statement to navigate to a particular screen depending on which Item is chosen from a Dropdown.

There are 5 screens to potentially navigate to:

Beef

Pork

Wild Game

Goat

Sheep

Navigation should occur "OnSuccess" of an order submission using a form. My current statement looks like this:

If(
"Beef" in DataCardValue36.Selected.Value,Navigate('Beef Screen',ScreenTransition.Fade),
"Pork" in DataCardValue36.Selected.Value,Navigate('Pork Screen',ScreenTransition.Fade),
"Wild Game" in DataCardValue36.Selected.Value,Navigate('Wild Game Screen',ScreenTransition.Fade),
"Sheep" in DataCardValue36.Selected.Value,Navigate('Sheep Screen',ScreenTransition.Fade),
Navigate('Goat Screen',ScreenTransition.Fade))

No matter what I choose - the data gets written back correctly, but I'm only navigating to the 'Goat Screen", which is my "Else" option after it evaluates the first 4.

What am I missing?

I don't know what the column name of the datacardvalue36 card is BUT

in your onsuccess

Switch(Self.LastSubmit.MeatColumn, "Beef",Navigate('Beef Screen',ScreenTransition.Fade), "Pork",Navigate('Pork Screen',ScreenTransition.Fade), "Wild Game",Navigate('Wild Game Screen',ScreenTransition.Fade), "Sheep",Navigate('Sheep Screen',ScreenTransition.Fade), Navigate('Goat Screen',ScreenTransition.Fade) )

switch up your condition. instead of "Pork" in DataCardValue36.Selected.Value use DataVardCalue36.Selected.Value="Pork", also include one for sheep, if all fail thats good information. Might also be better to pull from the exact dropdown and not just the datacard value since im not sure of the datacard type and how its values could be pulled, selected might not be an appropriate modifier for it. I tested with just a dropdown and it works correctly with DropDown1.Selected.Value="Pork.

It doesn't show in my snip, but the formula is all red - saying the Switch statement has invalid arguments. Meat Column is actually "Critter Type' for column name.

can you hover over each part of that switch until you get a more detailed error message? it is written correctly so need to see why the error is populating

I initially had the statement written like that first. I was getting an incompatible type error with that - optionsetvalue vs text so I switched to this syntax.

Choice column in Dataverse.
I'm getting the Invalid argument type error here too - Pork, Beef, etc, are Text, it is expecting an OptionSetValue instead.

Will the submitted form always only have one selection?

If so, you can play with something like this, (mine here is written for SHarePoint so you will need to play with it slightly to adjust syntaxt for that column reference but

Switch(First(Self.LastSubmit.'Critter Type').Value, "Beef",Navigate('Beef Screen',ScreenTransition.Fade), "Pork",Navigate('Pork Screen',ScreenTransition.Fade), "Wild Game",Navigate('Wild Game Screen',ScreenTransition.Fade), "Sheep",Navigate('Sheep Screen',ScreenTransition.Fade), Navigate('Goat Screen',ScreenTransition.Fade))
