Wordpress Error while developing a plugin -"You do not have sufficient permissions to access this page."

Question

I have just started learning wordpress plugin development and got this error when I access the my plugin menu from admin.

Here is the code: importer.php

//*************** Admin function ***************
function oscimp_admin() {
    include('importer_admin.php');
}

function oscimp_admin_actions() {
    add_options_page("OSCommerce Product Display", "OSCommerce Product Display", 1, "OSCommerce Product Display", "oscimp_admin");
}

add_action('admin_menu', 'oscimp_admin_actions');

importer_admin.php

<div class="wrap">
<?php    echo "<h2>" . __( 'OSCommerce Product Display Options', 'oscimp_trdom' ) . "</h2>"; ?>

<form name="oscimp_form" method="post" action="<?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>">
    <input type="hidden" name="oscimp_hidden" value="Y">
    <?php    echo "<h4>" . __( 'OSCommerce Database Settings', 'oscimp_trdom' ) . "</h4>"; ?>
    <p><?php _e("Database host: " ); ?><input type="text" name="oscimp_dbhost" value="<?php echo $dbhost; ?>" size="20"><?php _e(" ex: localhost" ); ?></p>
    <p><?php _e("Database name: " ); ?><input type="text" name="oscimp_dbname" value="<?php echo $dbname; ?>" size="20"><?php _e(" ex: oscommerce_shop" ); ?></p>
    <p><?php _e("Database user: " ); ?><input type="text" name="oscimp_dbuser" value="<?php echo $dbuser; ?>" size="20"><?php _e(" ex: root" ); ?></p>
    <p><?php _e("Database password: " ); ?><input type="text" name="oscimp_dbpwd" value="<?php echo $dbpwd; ?>" size="20"><?php _e(" ex: secretpassword" ); ?></p>
    <hr />
    <?php    echo "<h4>" . __( 'OSCommerce Store Settings', 'oscimp_trdom' ) . "</h4>"; ?>
    <p><?php _e("Store URL: " ); ?><input type="text" name="oscimp_store_url" value="<?php echo $store_url; ?>" size="20"><?php _e(" ex: http://www.yourstore.com/" ); ?></p>
    <p><?php _e("Product image folder: " ); ?><input type="text" name="oscimp_prod_img_folder" value="<?php echo $prod_img_folder; ?>" size="20"><?php _e(" ex: http://www.yourstore.com/images/" ); ?></p>


    <p class="submit">
    <input type="submit" name="Submit" value="<?php _e('Update Options', 'oscimp_trdom' ) ?>" />
    </p>
</form>
</div>

Any one can figure out what I am doing wrong.

Answer 1

The problem is fourth parameter. I have removed the spaces from the fourth parameter with _ and it works.

Thanks for your help...
