Thanks for your response. I am a complete beginner here and this is code that is already in place that has been handed on to me and I am just trying to incorporate some basic validation for the email field so that user cannot submit unless an @ or . are atleast present...I have looked through the link to the other thread but I am unsure how I would represent that within what I have?

Hi, I have a details screen where visitors to the website can leave their contact info. I have some javascript rules to validate some of the fields when the visitor is filling them out so they cannot leave certain fields empty. I have an email field where aswell as stopping the visitor leaving the field blank i want a validation check so it looks for the presence of "@" and a "." within the field. But I am having trouble getting this implemented. Currently my code for the blank checks looks like this (with the email field in the last block) :-

</script><script language="javascript" type="text/javascript">function validate_form ( ){valid = true; if (document.networkOpportunity.contactName.value == "") { alert ( "Please enter the name of the contact for the opportunity." ); document.networkOpportunity.contactName.focus(); document.networkOpportunity.contactName.style.backgroundColor = "#d7edf8"; valid = false; } else if (document.networkOpportunity.companyName.value == "") { alert ( "Please enter the company name that the opportunity is for." ); document.networkOpportunity.contactName.style.backgroundColor = "#FFFFFF"; document.networkOpportunity.companyName.focus(); document.networkOpportunity.companyName.style.backgroundColor = "#d7edf8"; valid = false; } else if (document.networkOpportunity.serviceRequired.value == "") { alert ( "Please enter the details of the service you require." ); document.networkOpportunity.companyName.style.backgroundColor = "#FFFFFF"; document.networkOpportunity.serviceRequired.focus(); document.networkOpportunity.serviceRequired.style.backgroundColor = "#d7edf8"; valid = false; } else if (document.networkOpportunity.contactEmail.value == "") { alert ( "Please enter the email we can contact you on." ); document.networkOpportunity.serviceRequired.style.backgroundColor = "#FFFFFF"; document.networkOpportunity.contactEmail.focus(); document.networkOpportunity.contactEmail.style.backgroundColor = "#d7edf8"; valid = false; }

Any help with how to add the extra validation on the contactEmail field to look for "@" and "." will be greatly appreciated.
