Hi there,

I am trying to add a check on validation of my form. The form enables users to input size and 

price of products. For the size I have a picklist (dropdown) of available fluid measures 

(25 ml, 50 ml, 75 ml etc.). This field is called 'Size'. Sometimes, however, the user might 

not know the actual size of the product in fluid measurements. In that case I would like them 

to provide a description of the size in a single line field (Operator_Name_for_Size). This is 

the code that I am using, but when I make an entry without filling in size (ie. leave it 

on 'Select') the system accepts the record.

if ((input.Size == null) && (input.Operator_Name_for_Size == null)) 

{ alert ("If fluid measure is not available, please enter a description 

of the size"); cancel submit; }

Can anybody help?

with thanks
