Error al multiplicar

hola gente nesesito ayuda porque me sale un error al tocar el boton calcular

What about revealing the exact error message?
Unfortunately your screenshot is of bad quality... also next time switch the language to English before taking a screenshot...

My guess is, you forgot some data validation before doing the calculation i e. check, if the textboxes are not empty before calculating...

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

I need help with this program. At one point, the total calories appeared but with a number that seemed random and changed even though I didn't change the data. I'm trying to fix it and now all the totals appear as 0.
I would really appreciate it if anyone could help me.
