I want my 'special instructions' field to display specific instructions when certain conditions relating to my 'customer' field are met.
For example... if 'customer' = "Fred's Bakery", I want the text "4-way entry pallets must be used" to be displayed in my 'special instructions' field.
If 'customer' = "John's Fruit and Veg Co.", I want the text "Apply labels to four sides of pallet. Do not stack more than 2 pallets high" to be displayed in my 'special instructions'
I'm sure this is a real simple one to solve.
