You should use FOO=3D'$bla' instead of FOO=3D"$bla" -- with the latter, $=
bla
is evaluated while assigning -- with the first one, $bla is evaluated
while evaluating $FOO.

This means, with your current way, the variables and functions are all
computed while setting the prompt variable -- and then there is nothing
left to evaluate while printing the prompt :)
