How to append a condition for this validation not to execute for old documents?

Hi All,I have added a field ‘change’ and this field should not be visible in my old documents as i would like this field to be effected to my newly created documents.I have written a hide when formula for that new field and its hiding from my old documents.But the problem is when i execute or submit any old documents,the validation in the ‘Change’ field is prompting for a value to enter.As i have hidden that field,it should not prompt me.How can i restrict that field not to prompt the validation while working on old documents.What condition should i add for that?Can anyone please suggest a solution?

Hi,

Put Your hide-when formula in if condition in validation formula. Something like this:

@If (hide-when-formula; @Success; “”);

your-validation-formula
