Help with "Step Timing Calculator"

Can anyone advise me on the following.

When I open the “Step Timing Calculator”, I can high light the numbers in the yellow fields but I can't get them to change. (I've never used a spread sheet before).

How do I get this program to cooperate?

Thanks

A picture is worth a thousand words

When the yellow cell is highlighted the value appears in the long edit box above the spread sheet.

Edit that and it will be reflected in the cell

Arceye,

Once again “illustration is the best instruction”.

I am able to get the field to “high light”, I can even select the number in the field and give it a black background, but the numbers will not change.
Is there some kind of permission I need to adjust in the spread sheet program?

Is there a better way to address "Tuning Steppers"? (I have stalling problems on Y & Z).

I see, the document is set to read only.
What is the best way to change this?
