IF functions not displaying due to incompatible types for comparison

[J_Taylor]

I am having an issue where an icon is not being displayed when first loading the app because the variable has not been initialised. I tried to get around this by having an IsBlank or IsBlankOrError function along with an If statement, but it keeps coming up with the error. The error is specifically:

Incompatible types for comparison. These types can't be compared: Text, Number.

I previously has the variable set to a Boolean and I still received the same error (e.g., "Text, Boolean").

The function is: If(IsBlankOrError(Help=0), true, Help=0). Since Help does not have a value, I am getting an error at Help=0 (both). I tried to get around this by the IsBlankOrError part which does not seem to see that Help=0 is an error. Previously, I had If(IsBlank(Help), true, Help=0). This still had an issue with the latter Help=0 - even though it would not need to evaluate that section due to the IsBlank(Help) which would then be true.

I hope this makes sense. Any assistance would be great.

Hey @J_Taylor 

Just a few ideas to start with would it help if the variable was initialised onstart and set to 0? 

Also is help being set to text at anypoint does Help = "0"

with the quotes make the error disappear?

How is Help being Set :)?

If that does not fit your needs

Thanks for the ideas, @AJ_Z. 

I tried setting Help to text "On" and "Off" [Set(Help,"On")]. I don't get an error anymore. However, it does not display on startup. The code is: If(IsBlank(Help), true, Help="Off") - which is equal to true at the start. However, it still seems to be invisible. 

How does one set Help to a value on start?

To set it on start

First find the App and click on it it will be above the first screen:

then when you click it change the property to onstart:

as it usually shows startscreen

then inside of here set the variable:

whenever the app starts it will now set it.

as you are in edit mode make sure you run onstart to initialize the variable for you:

so click three dots and run onstart

Thanks, @AJ_Z.

I was able to set Help as false from the beginning which made everything much easier. Thank you for the OnStart idea to bypass the whole issue.
