    copied!<p>Could someone offer me some advice as to form validation that restricts entry of a number below 5. I have got a donation form, simply an amount input field and a submit button to paypal.</p> <p>What form validation shall I use to restrict submission of the form if the amount value is below 5 (for £5.00).</p> <p>The form is below:</p> <pre><code>&lt;form target="paypal" id="donate" action="https://www.paypal.com/cgi-bin/webscr" method="post" &gt; &lt;div class="span6 text-center"&gt; &lt;input type="hidden" name="cmd" value="_cart"&gt; &lt;input type="hidden" name="business" value="SECRET-ID"&gt; &lt;input type="hidden" name="lc" value="GB"&gt; &lt;input type="hidden" name="item_name" value="General"&gt; &lt;input type="hidden" name="item_number" value="GEN"&gt; &lt;div class="input-prepend input-append"&gt; &lt;span class="add-on"&gt;£&lt;/span&gt; &lt;input class="span12" name="amount" value="5" placeholder="Enter Donation Amount" id="appendedPrependedInput" size="20" type="text"&gt; &lt;input type="hidden" name="currency_code" value="GBP"&gt; &lt;input type="hidden" name="button_subtype" value="products"&gt; &lt;input type="hidden" name="no_note" value="0"&gt; &lt;input type="hidden" name="cn" value="Add special instructions to the seller:"&gt; &lt;input type="hidden" name="no_shipping" value="2"&gt; &lt;input type="hidden" name="add" value="1"&gt; &lt;input type="hidden" name="bn" value="PP-ShopCartBF:btn_cart_LG.gif:NonHostedGuest"&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="span6 text-center"&gt; &lt;div class="controls"&gt; &lt;a id="buynow" class="btn btn-danger" href="#" rel="nofollow" onclick="document.getElementById('donate').submit(); return false;"&gt; &lt;span style=""&gt;Donate via PayPal!&lt;/span&gt;&lt;/a&gt; &lt;noscript&gt; &lt;style&gt;#buynow { display: none; } #page_theme #donate input { display: inline; }&lt;/style&gt; &lt;input type="submit" class="btn btn-danger" value="Donate via PayPal!"&gt; &lt;/noscript&gt; &lt;/div&gt; &lt;/div&gt; &lt;img alt="" border="0" src="https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1"&gt; &lt;/form&gt; </code></pre>
