I have the following code

  InputField[Dynamic[t], Number, ImageSize -> 30]
  PDF[NormalDistribution[μ, σ], t],

which doesn't result in

"f(inputfield) = result of PDF calculations based on input"

Any ideas?

No code formating after 7 questions? Does'nt look like you've put much effort into this Q... –  Ajasja Jan 24 '14 at 20:22
?? I've read and tried for the past two hours - wondering if I'm missing something easy or obvious - or trying to do something the wrong way. –  Fred Schenkelberg Jan 24 '14 at 20:40
No, no, I'm talkinig about the time you needed to write the Q. It's very polite to at least format the code you present using either 4 spaces or ``. In the other questions somebody else has taken the time to do that for you. Good formating will increase the chance of a good A. –  Ajasja Jan 24 '14 at 21:24
Ajasja is talking about post formatting. About the question, I think you should keep in mind one commonly quoted phrase: everything is an expression. What your code does is multiplying the parts in Style`s first argument. Take a look ar Row, Grid and related tutorials, e.g: tutorial/FormattedOutput. –  Kuba Jan 24 '14 at 21:25

You cannot simply put random expression or strings separated by a space in a sequence, because Mathematica interprets this as multiplication:

"oh" "my" "god"
(* "god" "my" "oh" *)

What you probably want is

Style[Row[{"f(", InputField[Dynamic[t], Number, ImageSize -> 30], 
   ")=", Dynamic@PDF[NormalDistribution[\[Mu], \[Sigma]], t]}], 16]

which uses Row.
