VBA - Writing PDF Form Fields with VBA from EXCEL worksheet

Good evening,

I'm writing data from EXCEL to a PDF with formfields. NUMBERS are fine but STRINGS are not acceptet.

Dim AcroExchApp As Acrobat.CAcroApp

Dim AcroExchAVDoc As Acrobat.CAcroAVDoc

Dim AcroExchPDDoc As Acrobat.CAcroPDDoc

Set AcroExchApp = CreateObject("AcroExch.App")

Set AcroExchAVDoc = CreateObject("AcroExch.AVDoc")

Set jso = AcroExchPDDoc.GetJSObject

jso.getField("Text1").Value = text1

If text1 is "1" it works

If text1 is "ABC" I get the error '13'

Someone can help me on this topic ?
