PHP Code:

format(query, sizeof(query), "UPDATE `garages` SET `garageOwnerID` = '%d', `garageOwned` = '%d', `garagePrice` = '%d', `garagePlayerSellPrice` = '%d', `garageSize` = '%d' WHERE `garageID` = '%d'",
    GarageInfo[gid][garageOwnerID],
    GarageInfo[gid][garageOwned],
    GarageInfo[gid][garagePrice],
    GarageInfo[gid][garagePlayerSellPrice],
    GarageInfo[gid][garageSize]);
    mysql_query(g_SQL, query); 


Here is your problem pal, you forgot to put the enum of the garage id..

change it to this..

PHP Code:

format(query, sizeof(query), "UPDATE `garages` SET `garageOwnerID` = '%d', `garageOwned` = '%d', `garagePrice` = '%d', `garagePlayerSellPrice` = '%d', `garageSize` = '%d' WHERE `garageID` = '%d'",
    GarageInfo[gid][garageOwnerID],
    GarageInfo[gid][garageOwned],
    GarageInfo[gid][garagePrice],
    GarageInfo[gid][garagePlayerSellPrice],
    GarageInfo[gid][garageSize],
    GarageInfo[gid][garageID]);
    mysql_query(g_SQL, query); 


That would do.
