document.getElementById(the_div).style.display=the _change;
}

when the alert is fired it always tells me reservecash

when i select credit card i still get the alert reservecash when it should be reservecredit

Then you can't be calling the JS function correctly. The div names must be enclosed in ' ' single quotes when calling the changeDiv function.

That can't be right because that's telling it to look for a div called the_div which doesn't exist.

Hi,

I am using this function

Code:

function calloptionpay()
{
var sel_payway = document.getElementById("payway")
var getpayway = sel_payway.options[sel_payway.selectedIndex].text
if(getpayway=="Cash")
{
changeDiv('reservecash','block');
changeDiv('reservecheck','none');
changeDiv('reservecredit','none');
}
else if (getpayway=="Check")
{
changeDiv('reservecash','none');
changeDiv('reservecheck','block');
changeDiv('reservecredit','none');
}
else if (getpayway=="Credit Card")
{
changeDiv('reservecash','none');
changeDiv('reservecheck','none');
changeDiv('reservecredit','block');
}
var creditcardflag
creditcardflag="Yes"
document.getElementById("creditcardflag").value = creditcardflag;
}
function changeDiv(the_div,the_change)
 {
document.getElementById('the_div').style.display=the_change;
  }

it works no errors but the divs dont change

This line:-

Code:

document.getElementById('the_div').style.display=the_change;

should be:-

Code:

document.getElementById(the_div).style.display=the_change;

In your previous post the function seems to be called changeDivcr. Are you calling the correct function with the correct variables?
