"I only display the relevant parts..since everything is working fine except getting hte php variable to the server side"

Javascript is client-side.
PHP is server-side.

You can't do it this way. You may hava a look at the XmlHttpRequest object.

As previously stated JavaScript is client side and php is Server side so you need to send the data from the browser to the client. This can be done by submitting a form (POST data) or by sending a new Http request(GET data) both of these will then generate a new HTML page.

Another alternative is to use Ajax that would mean that you only need php to send the modified page data.

I certainly know that it can be done..and I know about the client-side and server side issues...and you dont need XML to do it

Ok the following worked:
Create a hidden form object...
Create a javascript function that writes the value of the form object thisform.formelement.value = javascriptvalue

Submit the form and retrieve the value

You might know that...but that is what I wanted

No one said that you needed XML. What we were saying is that you need to send the data to the server. A form (POST data) is one way. Anyway it's good that you have sorted it out

First, let me thank you all for your help..especially you graemef this is not the first time you help me out when Iam stuck...
I think I formulated my previous reply wrong...I should revise my netiquette paper :P. About the XML thing I was referring to the XmlHttpRequest note by datbenik.

Thanks Again
