Hi,

I have on my local machines IE10; at the client location they are running IE10 and we both have the exact same version all updated.

On my machines here I can run the pages without any errors and the validation works no problems.

Same Browser and OS on the client machines is giving JavaScript errors and the code won’t work.

Strongly enough the line “form.Addr1.value.length” passes no problems; but if fails at “else if (form.City.length < 1) {” with an error of “Error: Unable to get property 'length' of undefined or null reference”

REMEMBER THIS ERROR IS NOT HAPPENING ON MY MACHINES, only on the client machines; all of them.

<JavaScript Code>

<script type="text/javascript">

// Mike Belcher - mbdev@outlook.com - Post to the SendCustomerLetter.aspx page

function SubmitSendCustomerLetter() {

// GET THE VALUES WE NEED AND DO VALIDATION

var form = document.getElementById("OOStitleForm");

if (form.Addr1.value.length < 1) {

alert("Please Enter an Address")

form.Addr1.focus()

return false

}

else if (form.City.length < 1) {

alert("Please Enter a City")

form.City.focus()

return false

}

else if (form.CorrespTitleState.length < 1) {

alert("Please Select a State")

form.CorrespTitleState.focus()

return false

}

else if (form.Zip.length < 1) {

alert("Please Enter a Zipcode")

form.Zip.focus()

return false

}

else {

//alert("Validation Has Passed; lets run the code")

// Here we do the post

form.action = 'SendCustomerLetter.aspx';

form.target = 'SendCustomerLetterCorrespondence';

form.submit();

//return true

}

}

</script>
</JavaScript Code>

Makes no sense why the same browser on two different systems, one has errors and the other has none.

Any Ideas?
