According to the properties of the check box the 'On Value' is a 1 and the 'Off Value' is a 0. See screen captures below. I have tried both "1" and 1, both values mark the check box checked when document is displayed (Opened), but neither one saves when you save the document. Can you identify what the 'custom value' is for the checked and unchecked state?
Code snippet:
"form1[0].#subform[0].cbComplaint[0]").value = "1"
"form1[0].#subform[0].cbComplaint[0]").value = 1
Code to display document:
AcroExchPDDoc.OpenAVDoc("Test")
