Keeping form data when there is an error

I have a plugin with that has it's own data table and form template.
When a user submits the form with a missing required field, it takes me back
to the form with the error message, but the custom fields are being erased.

How do I re-fill in the form with already entered data?

Thank you,

In the form template you need to make sure that you have the value fields filled in with if tags - for example:

<input type="text" name="Surname" value="<%if Surname%><%Surname%><%endif%>"/>

and then in the script that is processing the form, make sure that you feed the variables back in when you display the error template - for example:

print Links::SiteHTML::display('template_name', { %$variables, main_title_loop => $mtl, error => $error });

I actually had the script part setup properly, but in my template,
I was making the following mistake, and it took me a while to
figure it out. So this is just a reminder and/or tip for anyone else.

When using (input type ="text"), the value goes in the <input ...> tag.
<input type="text" name="Surname" value="<%if Surname%><%Surname%><%endif%>"/>

When using (textarea id="Surname"), the value goes between the open and close textarea tags.
<textarea id="Surname" name="Surname" rows="3" cols="42"><%if Surname%><%escape_html Surname%><%endif%></textarea>

FYI, I was using textarea, and putting the value in the opening textarea tag... boo!
It looks like value is in there properly, but it is wrong. Just very hard to notice. <g>
So, don't make this mistake. This example is broken, but at a glance looks correct.
<textarea id="Surname" name="Surname" value="<%if Surname%><%Surname%><%endif%>" rows="3" cols="42"></textarea>

Basic html, duh. Couldn't see the forest through the trees.
