Hi Paul,
Thanks again for your help, it mates sense now but I think Im sticking on a couple of things, this is whats in the script box now when you highlight the checkbox:
form1.#subform[0].Taxi::preSubmit:form - (JavaScript, client)
if (taxi.rawValue==1) then
form.Mobile.validate.nullTest="error"
form.Pickup-1.validate.nullTest="error"
form.Dropoff-1.validate.nullTest="error"
form.Collect-Date-1.validate.nullTest="error"
form.Collect-Time-1.validate.nullTest="error"
endif
What im stuck on is:
1) which point do i want this script? ie: in the 'show' box, I currently have selected 'presumbit*' which is the section where the code is now.
2) What langauage do I use? when I tried formcalc i got an error, it seems to be happier with javascript
Sorry to be a pain.
Ross
