<p align="center"><a href="INFORMATIONVENDORS1.pdf"><input type="button" value="Service Application" name="B1">
</a>
</form>
any ideas? thanks Brass

I would suggest, if you are using php. That you use this kina code.

I am sorry, but i dont see the need of all the extra information that you have filled both into the form tag, and the input tag.

thaks i will try that.

i tryed that and i this error message
The requested method POST is not allowed for the URL /INFORMATIONVENDORS1.pdf.
? iam not sure whats up. this is my form now.
<form name="open_PDF" action="http://informationvendors.com/INFORMATIONVENDORS1.pdf" method="post">
<a href="../INFORMATIONVENDORS1.pdf">
<input name="openPDF" type="submit" value="Application Form">
</a>
<p align="left">
</form>

if you click on the link here it takes you right too it. but not when i press the button.

well my main problem was i was trying to use a html button so the php wasnot working for it, this is how i fixed it.

<form method="GET" action="../informationvendors1.pdf">
<p align="center"><a href="../informationvendors1.pdf"><input type="submit" value="Application Form" name="B1"></a></p>
form method post would not work for the pdf file.
thanks for all your help. brass
