comment Find where an error occurred in a bunch of command line scripts
That's what I've been doing. But when you start having more participating scripts and/or logic gets more elaborated, it becomes harder... Sad that Mathematica does not have "exceptions" but the messaging approach.

@Mr.Wizard, I see!

comment Why is either Listable or HoldFirst not working?
As suggested by @Mr.Wizard, removing HoldFirst and then just using Column[DynamicInputField[Questions[[1, 3]], ContentType -> String], BaselinePosition -> Top] works for me.

comment LiftingWaveletTransform with irregular grids
Thanks @eldo, but b is just a {8,8} array and, therefore, representing a signal/function in a regular grid of $(i/8,j/8)$ points, that is not irregular.

comment Calculate support of given wavelet
Thanks a lot @Sektor. Your comment about the "impulse response" got me thinking and I was able to arrive to something similar to yours using the "PrimalHighpass" coefficients (it is most likely the same, but I will double check with yours; fantastic.)

comment Calculate support of given wavelet
Thanks a lot @Sektor, but the support of second graph (wavelet) seems to be around [-6,4], isn't it? This is what confuses me, because the values for $x$ where $\psi _{j,k}(x)$ is guaranteed to be zero don't seem be just outside of [0,$2^{-j}$].

I want to use DaubechiesWavelet.
