Those are read in checkoptions.asp like this.

<%
boption1=request.querystring("option1")
boption2=request.querystring("option2")
boption3=request.querystring("option3")
boption4=request.querystring("option4")

Many thanks tsuji!!
I have amended the following code, I would like to be able to 'pass' or show a result from CHECKOPTIONS.ASP to the 'pay' field on FORM.ASP depending on the result of the options chosen.
Any help would be fantastic!
Thanks.

I guess rewrite the PopDiv() will get you 90% to the solution, apart from some formatting.

function PopDIV(strDIV, strMessage) {
document.getElementById(srrDiv).innerHTML=strMessage;
document.calc.pay.value=strMessage;
