Hello guys,

I hope I can explain this right I have two input fields that require a price to be entered into them in order for donation to go through and submit.

The problem that I am having is that I would like the validation process check to see if one of the two fields has a value if so then proceed to submit. If both fields are empty then alert.

This is what I have in place now:

 function validate_required(field,alerttxt)
 {
 with (field)
 {
    if (value==null||value=="")
    {alert(alerttxt);return false;}
 else {return true}
 }
 }

function validate_form(thisform)
{
with (thisform)
{
    if (validate_required(input1,"Need a donation amount to continue")==false)
    {input1.focus();return false;}

    else if (validate_required(input2,"Need a donation amount to continue")==false)
    {input2.focus();return false;}
}
}

I would like to ultimately like to get this over to Jquery as well

Thanks guys any help would do

Matt
