I have a form with a drop-down for Title (Mr, Mrs, Miss, Ms)
I'd like the value of a hidden field for Gender to be automatically updated according to the title selected.

So I need:

If Title.value = Mr
Then
Gender.value = Male
Else
Gender.value = Female

Except I can't get the syntax right, could someone give me a hand? :confused:
