<description>&#60;p&#62;Greetings&#60;/p&#62;
&#60;p&#62;(I've submitted the following note to Support, but thought it might be useful to also post it to the forum. Hope that's okay.)&#60;/p&#62;
&#60;p&#62;I'd like my MachForm to do the following ...&#60;/p&#62;
&#60;p&#62;User enters number into Text Field A&#60;br /&#62;
User enters number into Text Field B&#60;/p&#62;
&#60;p&#62;This causes Text Field C to display the results of a formula like this:&#60;/p&#62;
&#60;p&#62;Text Field A x 1.6 + Text Field B = Text Field C&#60;/p&#62;
&#60;p&#62;Here is an example of this behaviour in a script developed by &#34;Calculoid&#34;&#60;/p&#62;
&#60;p&#62;&#60;a href=&#34;http://calculoid.com/#/calculator/1579&#34; rel=&#34;nofollow&#34;&#62;http://calculoid.com/#/calculator/1579&#60;/a&#62;&#60;/p&#62;
&#60;p&#62;Is the above possible with MachForm?&#60;/p&#62;
&#60;p&#62;Is there a way to make a modification to my MachForm that will allow this behaviour?&#60;/p&#62;
&#60;p&#62;Thanks for any ideas or suggestions.&#60;/p&#62;
&#60;p&#62;Best Wishes,&#60;/p&#62;
