Template sql errors, not again.... :( Errror 1064, I read sticky...

I did some template editing (just a little) and I get some errors some times, then I goto fix tables and it repairs them (BEST THING EVER!) How can I fix it though, cause it is kinda a pain to repair...

I got some more emails too, Whats wrong with it?

[Xenon]

there is no value set for parentid in the queryl.
but as you are using vb3, hacking is not supported here.
revert your files and templates and it should work again

[TheEnd]

? make it default?

[Xenon]

exactly

[TheEnd]

I don't wanna go back to purple, is there a way I can figure out what did make the error, and not do that to the table? (like pinpoint it?)

Ok, I read https://vborg.vbsupport.ru/showthrea...threadid=54118 and I didn't install any hacks. I added a button in the header and edited board color, boarder and table width. www.rec0n.com/cstrike/forums if you can take a quick look, lemmie know.
