Put the span inside a table cell, otherwise it will be invalid HTML.

Tanx did solved the first error but nog i have 2 more questions about the same lap of code:

all the errors are from my aspx webpage both errors give me the same text that says: document.Verzam elbladOverzicht .txtKlant1' is leeg of geen object

and the error points at Rule 5 and onther error points at the end of the HTML tag verry weird if you ask me if anyone has a solution that whoud be perfect Tanx guys

Can you translate that error message into English for me?

It'd also be a good idea to post your form code for the text box and drop down box.

Rather than the code from a different document, post the code from the same page, but the client-side version, i.e. when you view source in the browser.
