Radio Buttons update code

Just using some radio buttons which I don't often, and can't seem to get the syntax quite right on my update page, where the currently selection should show as checked.

What I have at the moment is:

<label class="radioSublabel_Narrow" for="Publication_Type__1">
Public&nbsp;<input type="radio" name="Publication_Type" id="Publication_Type__1" value="<?php if (!(strcmp($row_WADApublications['Publication_Type'],"Public"))) {echo "checked=\"checked\"";} ?>" class="formRadioField_Standard" <?php if (!(strcmp((isset($_GET["invalid"])?ValidatedField("publicationsupdate","Publication_Type"):"".$row_WADApublications["Publication_Type"].""),"1"))) {echo "checked=\"checked\"";} ?> tabindex="1"></label>
<label class="radioSublabel_Narrow" for="Publication_Type__2">
Private&nbsp;<input type="radio" name="Publication_Type" id="Publication_Type__2" value="<?php if (!(strcmp($row_WADApublications['Publication_Type'],"Private"))) {echo "checked=\"checked\"";} ?>" class="formRadioField_Standard" <?php if (!(strcmp((isset($_GET["invalid"])?ValidatedField("publicationsupdate","Publication_Type"):"".$row_WADApublications["Publication_Type"].""),"0"))) {echo "checked=\"checked\"";} ?> tabindex="2"></label>

With that, neither box shows as checked, but it if the value of 'Publication_Type' is 'Public' the first one should be checked, and if the value is 'Private' the second one should be checked. So I assume I just haven't got the syntax for the value right?

EDIT: OK, think I've got it - changes in bold below:

<label class="radioSublabel_Narrow" for="Publication_Type__1">
Public&nbsp;<input type="radio" name="Publication_Type" id="Publication_Type__1" value="<?php if (!(strcmp($row_WADApublications['Publication_Type'],"Public"))) {echo "checked=\"checked\"";} ?>" class="formRadioField_Standard" <?php if (!(strcmp((isset($_GET["invalid"])?ValidatedField("publicationsupdate","Publication_Type"):"".$row_WADApublications["Publication_Type"].""),"Public"))) {echo "checked=\"checked\"";} ?> tabindex="1"></label>
<label class="radioSublabel_Narrow" for="Publication_Type__2">
Private&nbsp;<input type="radio" name="Publication_Type" id="Publication_Type__2" value="<?php if (!(strcmp($row_WADApublications['Publication_Type'],"Private"))) {echo "checked=\"checked\"";} ?>" class="formRadioField_Standard" <?php if (!(strcmp((isset($_GET["invalid"])?ValidatedField("publicationsupdate","Publication_Type"):"".$row_WADApublications["Publication_Type"].""),"Private"))) {echo "checked=\"checked\"";} ?> tabindex="2"></label>

Although its not updating with the new value if I change it...

there is no value attribute for the radio buttons:

value="Private"

or:
value="Public"

So if I change it to:

<label class="radioSublabel_Narrow" for="Publication_Type__1">
Public&nbsp;<input type="radio" name="Publication_Type" id="Publication_Type__1" value="Public" class="formRadioField_Standard" <?php if (!(strcmp((isset($_GET["invalid"])?ValidatedField("publicationsupdate","Publication_Type"):"".$row_WADApublications["Publication_Type"].""),"Public"))) {echo "checked=\"checked\"";} ?> tabindex="1"></label>
<label class="radioSublabel_Narrow" for="Publication_Type__2">
Private&nbsp;<input type="radio" name="Publication_Type" id="Publication_Type__2" value="Private" class="formRadioField_Standard" <?php if (!(strcmp((isset($_GET["invalid"])?ValidatedField("publicationsupdate","Publication_Type"):"".$row_WADApublications["Publication_Type"].""),"Private"))) {echo "checked=\"checked\"";} ?> tabindex="2"></label>

It will update, but then both buttons appear as unchecked on the update page. What do I need for the button of the current value to appear checked on th update page?

I'll need to troubleshoot directly, see the private message section.

Sorry Jason - just double checking it, and it is working now. Must have been one of those ones where I had all the bits right, just not at the same time until now. Thanks again for having a look.

glad to hear it is working.
