Disabling button based on drop down and empty field

[theisogunro]

In the form below, I want the Update button to be disabled when the Cancelled or Rejected is selected from Request Status and if the Cancellation/Rejection Reason field is empty

 

Below is the formula I have.  Each If statement works independently but when I combine them together, it doesn't work.  Any ideas?

If(
    IsBlank(DataCardValue25.SelectedItems) && DataCardValue1.Selected.Value = "In Progress",
    DisplayMode.Disabled,
    DisplayMode.Edit,
        If(
        (DataCardValue1.Selected.Value = "Cancelled" && IsBlank(DataCardValue48.Text)) || (DataCardValue1.Selected.Value = "Rejected" && IsBlank(DataCardValue47.Text)), 
    DisplayMode.Disabled,
    DisplayMode.Edit
    )
)    

 Thanks!

You typically do not need an If() inside another If(). If() inPowerApps works like this

If( Condition1, ThenResult1 [, Condition2, ThenResult2, ... [ , DefaultResult ] ] )

So try rewriting your code like this

If(
    // Condition 1
    IsBlank(DataCardValue25.SelectedItems) && DataCardValue1.Selected.Value = "In Progress",
    // ThenResult 1
    DisplayMode.Disabled,

    // Condition 2
    (DataCardValue1.Selected.Value = "Cancelled" && IsBlank(DataCardValue48.Text)) || (DataCardValue1.Selected.Value = "Rejected" && IsBlank(DataCardValue47.Text)), 
    // ThenResult 2
    DisplayMode.Disabled,

    // Default Result
    DisplayMode.Edit

)

Thank you!  That worked!
