mysql_format(g_sql, query, sizeof(query), "UPDATE characters SET p_money = '%d' WHERE p_name = '%e'", pData[playerid][pMoney], ReturnName(targetID));

'pData[playerid][pMoney]' should be 'pData[targetID][pMoney]'

By the way, it should be like this:

PHP код:

pData[targetID][pMoney] += parameter;
ResetPlayerMoney(targetID);
GivePlayerMoney(targetID, pData[targetID][pMoney]);
mysql_format(g_sql, query, sizeof(query), "UPDATE characters SET p_money = '%d' WHERE p_name = '%e'", pData[targetID][pMoney], ReturnName(targetID)); 
    mysql_tquery(g_sql, query);
