Metrics and a strange behavior

Hello again,

I’m coming back with yet two other questions. I’m sorry if these sounds trivial, just trying to learn some more Tap Forms.

– For the first issue, I’ve searched the forum, I’ve searched the documentation, and I’ve searched inside Tap Forms. Maybe this isn’t possible in this version or else it eludes me. My actual project is to create my database of my 3D prints. Some of the metrics I calculate based on my settings and information I provide, I’d like to be able to add a way to read the number with its metric. For example : length of the filament used for a print : 336,95 m. Or the estimated weight of the print : 826 g. It does work for a currency, which is included, but I can’t find a way to edit that currency list to add my own metrics. Is there any way to do this ?

– The second issue, I’m not sure I understand. For this database, I have two forms. One of the forms contains the details about the models I have. The second form contains the record of every part I’m printing. I’ve nested inside the model the other form so that I can see all the parts I printed inside the model itself, as a list. And this works very fine. Every model has its own list, so all good. What I noticed though is that in the parts form, I estimate a weight in grams. The result of the formula always give a decimal number. So in that form, I limited the digit to 2 behind the dot. However, in the nested list, this value is not digit limited, giving its full decimal. Since it’s nested, I can’t find any way to restrict that column.

Here is the screenshots in order to make it a bit clearer. https://gyazo.com/3ea3879c9eec30826dbc754b407f44ad
This screenshot is the subform. All values are here nicely represented and as it should be.

And in this screenshot here, this is the same record nested into the main form. The last column doesn’t reflect the restriction to 2 digits.
Am I doing something wrong ?

Many thanks again for your help,

Fabrice
