Hoping for help, new IT guy, not much HTML experience, thrown a project, and this paypal button is the last piece

 Making  a donation by <strong>PayPal</strong> is just a click away for all PayPal account  holders. </p>
            <center><form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_blank">
<input type="hidden" name="cmd" value="_donations">
 
<input type="hidden" name="item_name" value="Community Treatment Solutions">
<input type="hidden" name="business" value="donations@ctsnj.org">
<input type="hidden" name="no_shipping" value="0">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="tax" value="0">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="bn" value="PP-DonationsBF">
<input type="image" src="images/paypalbutton.jpg" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
<img alt="" border="0" src="https://www.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form></center>

 it simply will link back to the same page, any assistance would be greatly appreciated!!! 

thank you very much! Its up and working now:

<center> <input type="hidden" value="_donations" name="cmd" /><span style="color: #949494;"> 
<input type="image" target="_blank" alt="PayPal - The safer, easier way to pay online!"
name="submit" src="/portals/0/images/paypalbutton.jpg" onclick="this.form.action='https://www.paypal.com/cgi-bin/webscr'" />
</span><input type="hidden" value="Community Treatment Solutions" name="item_name" />
<input type="hidden" value="donations@ctsnj.org" name="business" /><input type="hidden" value="0" 
name="no_shipping" /><input type="hidden" value="1" name="no_note" /><input type="hidden" value="USD" name="currency_code" />
<input type="hidden" value="0" name="tax" /><input type="hidden" value="US" name="lc" /><input type="hidden" value="PP-DonationsBF" name="bn" /> 
</center>

 but now i can't seem to get it to open in a new page, i tried moving the target="_blank" everywhere, and can't get it to open into a new window. Any resolution to this? I tried looking at other forums and haven't found an answer yet.

Thanks again,
