Mathcad Express Problem

Mathcad Express Problem

I am using Mathcad Express Prime 3.0 however some of my calculation blocks are greyed out and are not evaluating. This happened after I changed some variable names. Does anyone have a solution As nobody else uses Mathcad in my office?

In your sheet "automatic calculation" is turned off. So every time you change a variable, all expressions depending on that variable are greyed out (the old results aren't valid anymore) until the worksheet is recalculated (crtl-F9). You can turn on autocalc again at the calc ribbon, leftmost button.

EDIT: I just noticed that F9 or ctrl-F9 to recalculate a region or the whole sheet don't work in Prime if autocalculation is turned off. This does not make much sense. IMHO its abug or at least a failure in design.

Hard to say w/o anything to look at.

Maybe you attach one of the sheets which shows this behaviour, so we can see what you do.

Generally regions are greyed out

  • during (re)calculation
  • in Express if they contain "premium" features like programs or solve blocks
  • if you disabled it yourself

Please attach your worksheet.

Thanks all for the response. Please see attached worksheet. The problem starts from the end of the first page.
