Hi!

 

I have two dynamic fields CCNumber and CCNumberL4. CCNumberL4 is hidden. When a user enters a CCNumber and tabs out, I need the last 4 digits of the entered CCNumber to be populated automatically in the CCNumberL4 field. Can anybody help me with the client side validation script that I need to use for this functionality?

Any help is extremely appreciated. It's an emergency!

I would start with first just moving it over... So...

$(CCNumberL4) = $(CCNumber)

Once you have that working you can tweak it to just include the last 4 from a substring, or trim function etc..

Something like..
$(CCNumberL4) = $(CCNumber).substr($(CCNumber_FieldID).length - 5 )

That should do it...
