Getting compile error when i reference flashx module

Question

I am building an ioS/Android app in Flash Builder 4.7.
I am using the TLF classes to do some advanced text handling. so import :
          import flashx.textLayout.elements.TextFlow;
          import flashx.textLayout.formats.TextLayoutFormat;
however it says "Definition... could not be found" on those two lines, so my program won't compile.
I am including in my library path "tlfRuntime.swc", but that doesn't seem to fix it.
i realize that the TLF classes are not part of Flash, so i gotta include and specify to merge into the code the class, but i swear this code used to work before I updated to SDK 3.9 beta, which I have to do because IOS7 broke all my air apps, so I am rebuilding them now, and can't remember how I got this compile before.
i downloaded the Flex SDK, but this is an AIR app, so not sure what to do with the flex stuff anyway.
I am trying to build a standalone app, so is flex even part of the equation? It sure is confusing to me how Adobe mixes air and flex, why can't they just have a single environment, with different libraries...
any help is appreciated.

hi
you havnt assign event handler for button e.g.
Private Sub Plus_Click() handles Plus.Click
Oper1 = Val(Text1.Text)
operator = "+"
Text1.Text = ""
Equals.Enabled = True
End Sub
Private Sub Minus_Click() handles Minus.Click
Oper1 = Val(Text1.Text)
operator = "-"
Text1.Text = ""
Equals.Enabled = True
End Sub
Private Sub Multiply_Click() handles Multiply.Click
Oper1 = Val(Text1.Text)
operator = "*"
Text1.Text = ""
Equals.Enabled = True
End Sub
