I am creating a Validation Rule on the Account Name and Opportunity Name. Based on Israel, the rule should accept only English letters and special characters(&,_,! etc). IT SHOULD NOT let any user enter Hebraic letters.
I used this formule : AND(OR(ISBLANK( Name ), NOT(REGEX( Name ,"^[a-z A-Z]*$")))) BUT it does not let me enter any special characters.
Does someone have a solution in order to solve this request?
