I have 4 fields on a form. If the the user enters data in the first field, I want to move to the 4th field on the form. Does anyone know if there is an easy way to do this.

Here are a couple of ways, I'm sure there are more:

Method 1
field.two:
before.field:
if not isspace(field.one) then
attr.input = FALSE
else
attr.input = TRUE
endif

field.three:
before.field:
if not isspace(field.one) then
attr.input = FALSE
else
attr.input = TRUE
endif

Method 2
field.one:
after.field:
if not isspace(field.one) then
to.field(field.four)
endif

On the fields you want to skip set the form field attribute 'Input/Ref Expr." using the form editor.

Input/REf Expr. field.1 = "" (or " ", or 0, specific for the data type)

the to.field is exactly what I was looking for. Thanks Steve
