I'm new with Zoho and i've made some HUGH errors.

I have 2 forms.

Form 1 - Portfolio

Brand: Dropdown menu

Model: Text Field (no duplicated values accepted)

Form 2 - Sales

Date: Date value field

Brand: lookup value from FORM1

Model: lookup value from FORM1 (with a criteria that dependingo on the Brand you will see Model)

Now, the problem.

I've beenn updating form 1 - Portfolio, and as it was easier, i've deleted all the values and recreated them.

The problem is that now, all the registries that all the users made on Form2 - sales are with blank data on Brand and model fields.

Is there any way to update Sales records again without loosing all other fields (like added user for example).

Thanks in advance

Pablo
