Hi everyone,  
  
  
  
Does anyone know of a way to lock certain fields and NOT be overwritten if a lead submits a form for a second time? Let’s say I have a field “source campaign” and I record it as a hidden field on the contact form. But if they submit another form, i do not want the original value overwritten. So far I have not found a way to do this, any ideas?  
  
  
  
Cheers
