admin panel help - editing data

I have tried the code with and without the single quotes and there is the same column error either way. Is there another possible problem??

Sorry for the belated response, but try changing this:

Code:

---

$query = "SELECT (`date`,`venue`,`location`,`information`) FROM showdates";

---

to this:

Code:

---

$query = "SELECT * FROM showdates";

---

in the code to see if that fixes the problem.
Hope this helps; and again, sorry for the late reply.
