Conditional show not showing

[virginiascarlett]

Bug description

Hi,

I'm unable to get "conditional show" questions to work properly. I tried it both on my Mac and a Linux VM and I get the same result, even when I'm just running the unaltered template. This is not urgent for my purposes, but I'm wondering if it's a simple fix (I'm new to Shiny) or something deeper.

Steps to reproduce

install.packages("surveydown")
dir.create("test")
setwd("test")
surveydown::sd_create_survey(
  template = "conditional_showing"
)
shiny::runApp('test')

Expected behavior

Clicking "other" button on survey should trigger appearance of a new question.

Actual behavior

Nothing happens in the app, except that the Radio button is filled in. In the console, I get this warning/error:

Warning in value[[3L]](cond) :
  Error in condition evaluation: could not find function "sd_value"

I just tried this and everything ran. Based on the error message, it looks like you just need to use the latest version of surveydown. It shows you have 1.0.1 installed, but the latest is 1.1.3. The function sd_value() was added in 1.1.0, so that's why it's saying it can't be found.
