Can I sum two fields?

[James]

Hi all,

I have several fields in on tiddler, each filed represent a total score for a team.  Can I add them together and displace in the content?

For instance,
field_A = 30
field_B = 20

Display : {fieldA + fieldB} ????? it will shows 50?

thanks.

I think that the two closest things currently around are the calc macro by Tobias, which can only add a numeric value to a value in a field, not sum two fields, and the various action widgets I made in MathyThing which are all action widgets and require a button press to update the output.
If you know javascript than either one could me modified to sum two fields and display the output but in that case I would suggest the calc macro because it is much smaller.

Hi James,

I have updated calc with a new parameter called by

allowing you to specify both values independently

either as a number or as a TextReference.

Get the update from here:

calc @ tb5

For example:

<<calc 3 + by:7>>

=> 10

<<calc !!foo + by:!!bar>>

=> adds values from field foo and bar

<<calc A!!foo * by:B##bar>>

=> multiplies value from field foo at tiddler A with numerical data at index bar in data-tiddler B

Best wishes,

The number of arguments is limited? I can not calculate the expression: <<calc "tiddler A!!valor" + by:"tiddler B!!valor" + by:"tiddler C!!fvalor">>
