Hello, I am a beginner in this field.
I am trying to do an autofill for some information in the form I am creating
I am using Legacy Forms to create my forms

Within the form, I have a drop down list bookmark: Company, with the items X and Y as choices. On the field settings, Calculate on exit is selected

In another line or section of the document, I have inserted a field to auto input Phone numbers

My field code is
{IF { Company }="X" "(111)111-1111" {IF {Company}="Y" "(234)567-8910"}}}

After protecting the document, for example, selecting "X" from the drop down list doesn't update the field code I wrote for autofill phone numbers when a Company drop down list have been selected

Please give help or give me suggestions as what I am doing wrong.
Thank You
