Hi,

I have one table with an aleatory number of rows. Each row have, for exemple, two columns in witch I have created, with a loop, one checkbox for each column (the ID for each checkbox is assigned with the for... next cycle).

So, the final result is something like this:

Table-Title

Columnn1 Column2
Line1 checkbox(ID=11) checkbox(ID=21)
Line2 checkbox(ID=12) checkbox(ID=22)
..... ............... ...............
Total: (nº of checked checkebox) (nº of checked checkebox)

What I need is to be able to count the number of checked checkboxs that the user have selected, and put the total at the final of each column. Note that I don´t know how many checkedboxes I will have... that´s way the Id of each of them is assign with a for cycle...

How can I make this?

Thank you in advance :)

Ps: For instance, is this possible to manage with the "getTableByTagName, or any other method of the table object? Where can I find good information about the methods of this object?

document.all.d2.innerText=counter2;

Sorry, but I forgot to tell that the number of columns are random too....
Can I still use that method?
Thank you

No, Im making that table with the help of a XML tree...
Depending of that xml tree I create a table where in each row/column I create a checkbox, so the user can clik on it (check it) It´s like a questionare...

Thank you

if columns are unkown, and rows are unknown....will all columns and rows be equal in size? vs. column 1 has 25 rows, and column 2 has 76 rows?

Yes, they will be equal in size.

Thank you :)

You could use that method but you have to generate all cell id some like &quot;i&quot;+number and generate script for each new &quot;i&quot;+number value... (it's quite complicated... but possible)
