I created one formula field in contact object. When I give text with numbers(Before text and numbers(Ex: tsdhsgj12) or after text and numbers(Ex: 12gsdjgsjgfs)) in the input contact custom filed, it will save or allow only two digit numbers. Not displaying error message or validation messages. Could you please anybody help on this.
IF(ISBLANK(Test__c), 0, 1) in the formula field.
