Recalc with Range Variables

I have the following defined:
Min:=100 Max:=500
X:= Min,Min+50 .. Max
F(X):=X

F(X)=

This gives me a table from 100 to 500 in steps of 50, the problem I am having is if I change the 100 to say, 50 F(X) is not recalculated. It is set to recalculate. If I go to the F(X)= statement and delete the "=" sign and retype it, it then recalculates. Is there anyway to get Mathcad to do this automatically. Its Mathcad2000.
Thx

Are you sure you have automatic calculation turned on?

You need to set it from the menu selection in the Tools submenu

Yes, it is turned on. Other equations change when I change other variables. Just not that particular column. It may be changing in the background but not in the view.

After thinking about my last post, I thought I would graph the function. Sure enough, the graph changes but the table stays at the same values. Bug or Feature??

It's a bug in the integrity of the Mathcad installation.

The same set of expressions crashed Mathcad at home, but ran perfectly fine at work, with the same software load.

I have had the same problem with V7, 2000 prof and 11.

There are 6 identical (hardware-wise) PCs in my section, and two (mine and one other) have all sorts of niggly litle things like this with Mathcad that the rest don't. For instance, I also have a problem with the up-down scroll bars resulting in a left-right scroll and vice versa - but only intermittently!

I have reached the point where I just mutter rude things under my breath and press on - I can't see any way out of it, and I don't know that Mathsoft have any real answers, especially if the problem appears to installation dependent.

Mathcad seems to interact badly with stale video drivers, and also tends to want video acceleration turned off.

Some of the older versions Norton AV also have bad effects when scriptable components are embedded in the Mathcad sheets.

I would like to thank you both for all your input.

In Mathcad2000 the recalc feature is under the "Math" selection. There is "Autocalc", which is turned on. "Calc" (also performed by hitting F9) and "Calculate worksheet". Auto Calc and F9 give the save results. They do not update the tabulated data. However if I run "Calculate Worksheet" everything is updated. So at least I can do that and get results. Interesting that they do not have an "Auto Calc Worksheet" selection anywhere, or at least I can't find it.

Autocalc is supposed to work on the entire sheet. There is no separate autocalc for expressions.

Calc (F9) only works on the current selected expression and any colateral expressions.
