Hi Sarkut, I must apologise for my very badly worded post – I don’t mean to question your claim that you wrote it in JavaScript yourself!
Where I wrote, ‘I’ve seen similar calculators elsewhere, if you look at the page source it always seems to make reference to dq_estimate_wizard.cfm’
I should have clarified to what I was referring, viz. ‘I’ve seen similar calculators elsewhere, if you look at the page source on those sites it always seems to make reference to dq_estimate_wizard.cfm’
Sorry for any confusion!
