Message and negative value

Maxvl 12 Sep, 2018

Hello
The calculation is used in the form. The final value can be negative.

Please inform how to display an information message if the value is negative.

Thanks a lot

1) PHP action

return ($this->data("name of value", "default") < 0);

2) Event switcher, data source {var:switchname} , events true, false

Unfortunately it did not work out
Tell me what's wrong

Well is your data field actually called "T" ?

Maxvl 15 Sep, 2018

Yes

Try 1,0 or {value:true},{value:false} instead of true,false

And check your debug action to make sure T is returning what you want it to.
