I have Nintex forms on SharePoint 2013.
There is supposed to be a f(x) button next to the Condition panel of the Rules pane that brings up the Formula Builder dialogue. My screen doesn't show the button. I've tried it in 3 browsers, Chrome, FF, and IE.
That's okay because I can click to the side and the Formula Builder window appears.
But sometimes the Condition box expands so long that there is no space for the f(x) button to appear.
Please see the images below:


I can work around the f(x) button being invisible. But I don't know what to do when the Condition box become so long that I can't even get to the space where the f(x) button would be.
Please advise.
Thanks in advance.
