Help with hiding a button using Lotus Formula

Hi

I have been creating some simple forms in Lotus Designer but im having trouble making a button appear when I want it to.

I have 3 fields called 'Process_1' 'Process_2' and 'Process_3' which are a radio button with 3 selections, by default there is nothing selected, I want the button to appear when all three fields have been filled in.

So I created a button and hid it using the 'Hide paragraph is formula is true' option and entered the code :

Process_1 ="" & Process_2 ="" & Process_3 =""

Thinking that would do it, but it doesnt work..

Im pretty new to this so can anyone shed any light on it?

If you want all three to be non-empty for the button to show up, then you should hide the button when one of them is empty:

Process_1 ="" | Process_2 ="" | Process_3 =""

Try this formula:
@IsNull(Process_1) | @IsNull(Process_2) | @IsNull(Process_3)

and don't forget to check "Refresh fields on keyword change" int the field property of all three fields.
