# Tex problem?

I'm working on a post involving a lot of tex-formatted material, but each time I try to preview what I've written, the preview shows me stuff I wrote in previous posts, in different threads, completely unrelated to the tex material I just wrote (but mixed in with the ordinary text of the new post). What's going on?

Hmmm anyone else? Unfortunately it seems out tex expert has left the building.

I guess I'll just wait until this clears up. Otherwise the post will just be jibberish. (Of course, it may be that anyway).

I have encountered the same problem many times.
Don't write too many code lines one after another.With so many consecutive symbols ("}" i mean),it will be very hard to spot errors.

P.S.By that behavior,the compiler shows you you've give him a wrong code.It's not its fault by any chance.

Is there something wrong with this (other than that the tex tags are replaced by quote tags):
because when I preview ONLY that, it shows me the graphic for this INSTEAD:
which is a piece of inline tex code that I was previewing in the post I'm trying to format.

When you edit a correct tex code and introduce an error, an old formula is displayed. I also had this problem already.

I previewed both codes you have posted: the second one is correct, but for the first one I see the last latex formula I have posted in the homework forum... Thus I assume there is something wrong, but I cannot tell you where the error is.

$$\begin{array}{cc} \text{Variable} & \text{Meaning}\\ Q[i,k] & \text{At time "i"} \ \text{M is in state} \ q_{k} \\ H[i,j] & \text{At time "i"} & \text{the read-write head} \ \text{is scanning tape square "j"}\\ S[i,j,k] & \text{At time "i", the contents of} \ \text{tape square "j" is symbol} \ s_{k} \end{array}$$

Is that better...?

Not really. I'm trying to get the entries in each column to be left-aligned, and to be able to have some entries in the second column extend to several lines leaving the first column blank on those "continuation" lines.

Anyway, I didn't mean for this thread to become a new competing tex-formatting discusssion. I just wanted to alert the Admins to what I think is a board problem. Let's restrict the discussion here to whether this is a board issue or a code issue.

If anyone has suggestions on how to fix my code, let's continue that discussion in the "sticky" Latex typesetting thread in General Physics. Thanks all.

It was a code problem. Solved.

Into which category would you put the fact that subscripts can be used in \mbox, and they can be used in {array}, but not in \mbox in an {array}?

:rofl: Human error of course:It's not the compiler's fault,but this time,the programmer's...

ALWAYS HUMAN ERRORS.NOT NECESSARILY USER'S... :tongue2:
