Hi All I have a small install file as below. *<?php function resume_submit_install() { drupal_install_schema('resume_table'); } function resume_submit_uninstall() { drupal_uninstall_schema('resume_table'); } function resume_table_schema() { $schema['resume_table'] = array( 'fields' => array( 'uid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'default' => 0), 'name' => array('type' => 'varchar', 'not null' => TRUE, 'default' => ''), 'email' => array('type' => 'varchar', 'not null' => TRUE, 'default' => ''), 'altemail' => array('type' => 'varchar', 'not null' => TRUE, 'default' => ''), ), 'indexes' => array('uid' => array('uid'),), 'primary key' => array('name'), );* * return $schema; }* When I install the custom module, it installs without any warning/error. But on form submit, when I try to save some data, it gives warning (table does not exist). Can somebody help me to understand, what could be the issue. Thanks Austin
