Greetings,

I am using data validation and I want to compare against a certain pattern.  My requirements are:

Field A is a drop down list 

If field "A" = "X" then field "N" must start with the number 4 and be 7 characters long.  EX: field "A" = "X" ; "N" = "4123456" ::

that part does not seem to bad..  my custom pattern = 4/d/d/d/d/d/d

>>this is the part that is stumping me:<<

If Field "A"="Y" then field "N" can start with either a "7" or "8" and must be eight characters long: EX. field "A"="Y" N=81234567 ->OK  or N=71234567 ->OK

How do I validate the first character in a custom pattern to be either (7 or 8)?  ie: (7or8)/d/d/d/d/d/d/d

Thanks for your help

Hello and welcome to the forum!

For your second data validation (A=Y), you can actually separate your two conditions (7 or 8) using "OR" in the dropdown. So in this data validation, you will have a total of three conditions:

• A = Y (and)
• N = 7/d/d/d/d/d/d (or)
• N = 8/d/d/d/d/d/d

Hope that helps!

Thank you for the response.  1 more variable to throw into the mix that I did not explain before:

if A=Z

N="Non Applicable"  (or blank)

If I use the "OR" statement in the validation then the field is forced to not be blank (red star in field).  I tried creating a rule that if A=Z then to set N to a default of "NA" but for some reason it never sets "N" to the letters "NA"

You'll get a red asterisk in the control if none of the data validations are met. One thing to remember, rules only fire when the field's (within the rules) value changes. Therefore, N will only become NA, if you manually select Z from your A dropdown. If you wish this rule to fire automatically when you open or preview the form, you must set it in "Open Rules" instead. You can do so by going to InfoPath's Tools menu > Form Options > Rules.
