Problems with form validation

Hi all

A few weeks ago a nice man called Evertjan helped me create a form
validation system that took a table of four columns of checkboxes and:

- allowed only one checkbox in each row to be checked
- totalised the number of checked boxes in each column

The system works fine until you have more than 10 rows, at which point
the myrow substr(1,1) fails to correctly identify the row number
because it needs to extract two characters instead of one, and the
mycol substr also then doesn't work.

I'm a noob at javascript, so I'd really appreciate any help in adapting
the code (below). It works fine up until row 10, then it goes
pear-shaped.

Thanks in advance for any help.

I'm going to offer two answers to this.
The short (wrong though it works) answer could be to replace:
myRow = my.substr(1,1)
myCol = my.substr(3,1)
with the following:
var colRowRE = new RegExp("r(\\d+) c(\\d+)");
colRowRE.exec(m y);
var myRow = RegExp.$1;
var myCol = RegExp.$2;

The longer better answer is to change what you are doing.
Whether or not to use xhtml is a subject for debate. However, if don't
mark your code as xhtml if its not compliant.
Making it correct would be a good starting point then, making it
somewhat sematic and ditching the nested tables would be a good start
down the right path.
I'm going to offer up the following as an alternative starting point.
Maybe a more experienced javascript guru will post some code as an
improvement to this.

Many thanks for your help - I've tried the 'wrong' fix and it works
fine, as you say. I'm intrigued to know why you call it wrong, though?

The spurious code was added in by Dreamweaver when I did some changes
that way.

I'll have a go at the alternative version later, when I've got some
more time.

Many thanks again for your help.

I think, using a naming convention to establish the relationship
between elements is asking for trouble. Especially when html gives you
the means to establish the semantic of columns and rows.

mycol substr also then doesn't work.
simple change : Instead of "naming" them from 0 upwards, start at 10.
You'll then have 90 rows before needing more characters. If that's not
enough, start at 100 ... . Change the substr parameters accordingly, of
course.
If your page requires javascript in order to function, consider using
javascript to write the rather repetitive form structure, using loops.
