Can't find handler -- what does this mean? [solved]

[ittarter]

Hi,

Just bought Livecode and it's embarrassingly difficult.

I can get the answer function to display a text, but I can't set the text of my label lbl_total. The current error is "can't find handler" but I get other errors too, no idea what they mean. Is there a place where livecode error messages are explained?

Basically I want my app to add up a few boxes and display the result in a label... but I can't even get it to display "3". And I have no idea why. (I thought I followed the "Hello World!" model to the letter. Not sure why my app of differently named cards and buttons wouldn't work the same way.)

set text of lbl_total to "3" ## also doesn't work

I've also tried to be fancy with (under the button script)
on mouseup
calculate
end mouseup
(and then on the card script)
on calculate
put "3" into lbl_total
end calculate

Included is a hopefully helpful screenshot. Please end my suffering.

Is "lbl_total" a field? If so, try this:

Code: Select all

put 3 into field "lbl_total"

Label fields are also fields. Hope this helps.

Yay, thanks. I think I'm going to watch some video tutorials...
