So grateful, Jason - thanks!
Will immediately of course Get the corrected file, now.
Question (not a small one): Since I used all, and only, the tools provided - did not myself modify the code - what is good practice for the future? Of course, I would like to learn the moves that fixed it this time, but that will be for a little later down the road. Hence the question, good practice going forward at the moment?
For example, the custom Presets preserve most of the settings - but not all. The errant Email validation on street_1 is a current case in point. I have made this page at least eight times now, probably several more than that. I exhaustively go through all the settings each time. But a few of them - the validation type is a repeat case, every time - are always incorrect. Despite having 'overwritten' the Preset file when last corrected. I reset the errors naturally, but of course I do not know what code actually writes to the page.
Is there some way to edit the Preset file, so that it is 'solid' and not in error? Of course a page like this has _many_ such settings, so not a small thing to keep straight. (Nor to check each and every time the Preset is used to recreate the form … Incidentally, I do not overwrite an existing form; I always start fresh. Including, I delete the special CSS file the machinery generates, so that it is also fresh.)
Also probably worth knowing: DW (in my case CC 2014.1 release, on Mac 10.8.5) regularly crashes, when making the form. Probably restarted 15 or 20 times, since I have been at this one. Typically crashes when trying to write the file, but sometimes before. (I do regularly get rid of the .dat file, in Configuration, to prevent difficulty on that front.)
Obviously life would be a good bit better if that were not the case.
Again, I am so very appreciative. Let me get at the file now, hopefully to have it solid going forward. And on to the next form I have to create here (hence among others, the question about good practice going forward).
