Form submit and search query

wrong behaviour at pressing Enter

[mcibor]

I have such simple code:

<form name="enter" action="#" method="POST">
<table><tr><td>a1 <input type="text" name="a"></td></tr>
<tr><td><input type="submit" name="sa" value="a"></td></tr></table>
<br><table><tr><td>b1 <input type="text" name="b"></td><td><input type="submit" name="sb" value="b"></td></tr></table>
</form>

Where "a" is a form for getting some values, and "b" is a input to put search query. My problem is such, that when user writes something in "b" (search string) and presses Enter, the form is submitted with "sa" set, not as I would like "sb".
What should I do to correct this problem? Changing the position of "a" and "b" is not possible.
Summarizing, if a user presses Enter in "a" field I would like to submit "sa", if a user presses Enter in "b" field then I would like to submit "sb".
Thanks for any answer

I'm not clear why you have two submit inputs - you can send data from many text inputs with one submit. Is there ever a case where you want someone to be able to send "a"?

The first inputs and submit are for creating a new user, and the second input and submit are for doing search. Therefore I cannot and don't want to combine them. However if you know of some way to send search string without submiting I'm open to suggestions.

The real code is: input user; pass; pass again; submit New user.
input search; submit Do search

I use mozilla.
I would welcome any answer

How about two forms, then? Is there some reason they must be combined into one form?

Thanks Tedster!

After putting them into two separate forms it works fine!
