Check Code Commands

Create a Skip Pattern Using IF/THEN and GOTO

Use IF/THEN statements to create skip patterns based on the answers to questions in the form. This example creates code, which states that if the person answered No (-) for the Hospitalized field, then the cursor subsequently jumps to the field Was the patient treated with antibiotics? and skips the Hospital Admission date field.

  1. From Form Designer, Open the Ecoli.prj project.
  2. Double click on the FoodHistory_NoCheckCode form.
  3. Click Check Code or select Tools > Check Code Editor. The Check Code Editor opens.
  4. From the Choose Field Block for Action section, expand the node for Page 1 to see the various fields on the first page.
  5. Expand the node for the Hospitalized field.
  6. The action needs to occur after data are entered into the Hospitalized field.
  7. Double click on the after event.
  8. A block of code for the Hospitalized field is created and displayed in the Check Code Editor.
