I am trying to copy the Customers Field from the Service activity for into another field I have created on the form. The Customers field is defined as a Part List and when executing the on change event I am getting "This control only accepts strings or null as input." How can I make this work? I know I need to convert the data type or something just not sure how.
Here is my code.
function copycustomername()
crmForm.all.new_customernamecopy.DataValue=crmForm.all.customers.DataValue
