PHP Show if hides update fields, but they get overwritten with an empty string

Question

I have an issue with a page where some update fields are displayed depending on who is logged, for example:
<?php if ($row_Users['UserID']=="101"){ ?>
<input <?php if (!(strcmp($row_lodges['101_finalist'],"Yes"))) {echo "checked=\"checked\"";} ?> type="checkbox" name="101_finalist"  value="Yes"/>
<input type="text" class="rankfield" name="101_rank" value="<?php echo($row_lodges['101_rank']); ?>" />
<?php }  ?>
<?php if ($row_Users['UserID']=="102"){ ?>
<input <?php if (!(strcmp($row_lodges['102_finalist'],"Yes"))) {echo "checked=\"checked\"";} ?> type="checkbox" name="102_finalist"  value="Yes"/>
<input type="text" class="rankfield" name="102_rank" value="<?php echo($row_lodges['102_rank']); ?>" />
<?php }  ?>
The issue I have is that if User101 is logged in and updates fields 101_finalist and 101_rank, it overwrites 102_finalist and 102_rank with an empty string.
Is it possible to prevent each user from seeing the other fields for other users, and prevent the existing values for those other users not be overwritten?
Hope that makes sense!
Thank you.

That would mean multiple nominations when really there only needs to be one nomination per category in any given country.
It would be:
1, 345, 101, Borana Lodge, 7, 2, Yes, 1
1, 345, 102, Borana Lodge, 7, 2, Yes, 3
1, 345, 103, Borana Lodge, 7, 2, No, NULL
Instead of:
1, 345, Borana Lodge, 7, 2, Yes, 1, Yes, 3, No, NULL
Sorry, Lodge isn't in the nominations table, the list above is what is displayed on the site. Lodge gets looked up in the Ldoges table.
At the moment it works like this:
People can visit a website and vote for lodges in different categories, giving them a score out of 10 for each.
If a lodge gets a vote in a particular category an admin person creates a nomination for that lodge, in that category.
And the last bit is where judges login and tag the ones they think should be finalists.
