If Statement

[Reid]

How would I make a script for this?

If (

Table:Field = (empty); continue with script ; display message "Serial has already been used"

)

I'm trying to make this part of a button. I'm using it for an invoice. The button adds items to the invoice. I don't want it to add the item if its already been shipped before. I'm able to do everything except the if statement to make it stop if there is already a date in the field.

If (IsEmpty(Field) ; do pass actions ; do fail actions )

How would I do this in script manager?

[efen]

If [field = ""]

perform whatever script steps needed here

Else

Show custom dialog"serial used"

Exit script

End if

Thanks for the correction efen. I was thinking xls.. Sorry for the mistake.

If isEmpty( field).

FileMaker reps are always pretty adamant that = "" is not reliable.
