rent vehicles on dialog help

Hiya there lads, I'm kinda stuck wiv my Rent Car system so I decided to ask for a hand from ya'll scripters who might give me a clue how to set it up.

So the system I want to create it up is a renting car system on a dialog, similar to a Dealership one, with stock and price label, for example when I open up the renting menu it must show sumthin like this:

Infernus - (Stock: %d) - (Price %d)


but this is not the case why I'm here, the case is that I keep failing with the mysql connection of the cars which I'm supposed to insert them in the Renting System.

I've got the commands ready, dialogs, table `rentlv` (in phpymadmin) but one thing I don't have is the function or the Public which is supposed to read or transfer the information from my phpmyadmin to my server (rent dialog system)

That's what I want to know how can I connect the renting vehicles from my phpmyadmin table to my server so I get the actual number of cars in Stock and the Price of them, I tried follow a Dialog Dealership, but the system differs a bit...

anyway... if I didn't make myself clear enough I'll be happy to re-answer your question, and also I'm hopeing to get the smallest clue from ya'll Ty bros!
