[gourav96]

Hi,
I am new in virtuemart2.x i have an issue can this issue is fixed through custom field

* I have an product having attribute date and city i.e on a  particular city that product is  available  on a particular date.
For Example if i select city e.g; WE SEND SPAM from the select list then in the date select field auto display the particular date, that date was set in the back-end like in a relational manner with the city lists.


I mean to say that how add a relation between City and date so that when someone select particular city then the corresponding related date will be display.

The city and dates are enter through custom fields but in a relational manner.

Help me to out  .
