problem with if-else in shiny

[DomenicoRe]

Hi everybody,
i am trying to do an app with shiny but i have a problem with if condition.
in input an user insert "spessore"
if this is 87.31 then it works, in output it gives me some information. If instead this is 87.16 then it doesn't give me information and in R I have this problem: Warning: Error in data.frame: object "thickness_fin" not found
1: shiny :: runApp
Warning: Error in renderText: object "thickness_fin" not found
96: renderText
95: func
82: renderFunc
81: output $ sentence
1: shiny :: runApp

To you a small excerpt:
if (spessore==87.16 || spessore==87.26 || spessore==87.31 || spessore==87.41 ||
spessore==87.66 || spessore==87.89 || spessore==87.99){
if(media>=1.25 && media<=1.5){
spessore_fin<-"Aggiungi 0.04"
}else if (media>=1.18 && media<1.25){
spessore_fin<-"Aggiungi 0.03"
}else if (media>=1.1 && media<1.18){
spessore_fin<-"Aggiungi 0.02"
}else if (media>=1 && media<1.1){
spessore_fin<-"Aggiungi 0.01"
}else if (media<=0.71){
spessore_fin<-"Riduci di 0.01"
}else {spessore_fin<-"Rimani invariato"}
}

Tahank you.

Hi, welcome!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at these resources, to see how to create one for a shiny app

Shiny debugging and reprex guide

Shiny issues can be challenging to resolve relative to other problems with your code or statistical methods. Shiny apps are often large, complex projects with interacting files. When seeking help from others it is considered polite to: First, do your best to work through RStudio's debugging tools to diagnose your issue on your own. Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue. You can do this with a reproducible example ("reprex"). Shiny Debugging Errors in Shiny code can be difficult to track down. If you don't know where your problem is coming from, you can track it down with some o…

This is my guess because, as nirgrahamuk said, we don't have a reprex.

thickness_fin is not a variable in your code, but spessore_fin is. According to The Cambridge Dictionary, "spessore" is Italian for "thickness."

Your code may be improperly bilingual. See if there's a thickness_fin you need to replace with spessore_fin.
