Creating a trigger condition that advance after 4 numbers entered
I am working on a project right now where I prompt the user to enter a sort of verification question, in this case I am asking for the last 4 digits of their SSN. They will then be prompted later to enter them again (using this method here: http://community.articulate.com/forums/p/31893/172296.aspx#172296 to "verify")
I have made a text variable and a submit button. However, I would like the user to only be able to click submit then jump to the next slide if they have entered 4 digits into the text variable field. I can't seem to figure it out within the trigger conditions option. Any ideas?
