removing State information

Hello,
Could you please advise what are the code lines groups that must be removed in order to delete the the STATE information ? (State = US country part).
I tryed myself in the users_Profile.php page : I removed the big paragraph concerning the state :
<p>
<label for="UserState">State:</label>
……………………………………….. Up to ………………………………………
Please choose a state.
</span>
<?php //WAFV_Conditional users_Profile.php usersProfile(10:)
}
}
}?>
</p>
However, after this operation, there are malfunctions in :
- ...Admin/users_Results.php page >>> The first name and last name don't appear.
- . ..Admin/users_Detail.php page >>> The first name, last name,adress, city,Zip code, don't appear at all.
To make sum up : how removing the state information (that doesn't exist in my country) without modifying the rest of the site ?

Thank you for your help in advance.

Replace the state list with a hidden form element of the same name that has the value set to "n/a", for example:

<input type="hidden" name="state_province" value="n/a" />

Thank you Jason,

However, I cannot find " <input type=" . . . " name=" . . ." value=" . . ." /> For state in the users_Profile.php page.
I suppose that is because it is a drop-down menu.

There is only :

<select name="UserState" id="UserState" onBlur="if (document.getElementById('stateServerValidation')) document.getElementById . . .

etc.

Can you tell me how to do the same thing (erasing the state request / info so that the enduser don't see the state ) with this drop-down menu.

Thank you for your help.

Replace the select list:

<select name="UserState" id="UserState" onBlur="if (document.getElementById('stateServerValidation')) document.getElementById('stateServerValidation').style.display='none'" onChange="if (document.getElementById('stateServerValidation')) document.getElementById('stateServerValidation').style.display='none'" >

            <option value="" selected="selected" <?php if (!(strcmp("", (ValidatedField("usersRegistrationfull","UserState"))))) {echo "selected=\"selected\"";} ?>>Choose a state</option>

          [...etc...]

          </select>

with a hidden form element of the same name, with the value set to "n/a":

<input type="hidden" name="UserState" value="n/a" />

Thank you for your help !
