I am doing the following app.
There is a drop menu (called app.menu) in which the user selects one of the options there, then, he clicks on the button and a certain value appears on the box (called app.caja), as you can see in the code below.
Here is the code in the button callback:
function botonButtonPushed(app, event)
if app.menu.Value=='engranaje'
app.caja.Value=1
elseif app.menu.Value=='ruedaa0'
app.caja.Value=2
elseif app.menu.Value=='ruedaav'
app.caja.Value=3
end
end
The issue is that it works perfectly when the options in the dropmenu are "short" words as "a" or "b" with one or two letters, but when the are full words (like the case here) it doesn't work and appears the following error:
Matrix dimensions must agree
How can I solve this? Thank a lot
