Hi, I'm not sure how one should react to these kind of titles mentioned above.
Although I know editing is encouraged you must never change the meaning.
I edited this question because I thought it was the right thing to do and might help the OP to get an answer, but this is MY interpretation of the problem, and in some cases I might guide to something misleading and wouldn't want that.
My change was from:
Simple form is driving me crazy! please check
Problem with HTML form - PHP not inserting into Database correctly
Where should the limit be in general terms?
