Data Types confuse me

I am getting a message when I add statement below that mentions invalid argument type.

UpdateContext({varDateError2:If(ddNumberofDays>txtDaysDiff,true,false)});

ddNumberofDays is selection from a dropdown. 

txtDaysDiff is difference between these dates from date pickers computed from expression below.

DateDiff(dpFromDate,dpToDate,Days)+1


I know my data type are different but not sure how to fix. Thank you in advance for your advice.

Hi @PowerAWantabe ,

You should just need this

UpdateContext(
   {
      varDateError2:
      Value(ddNumberofDays.Selected.Value) > Value(txtDaysDiff.Text)
   }
);

You need to turn both text items to numbers and you do not need the If/true/false as this is inferred.

Hi Warren, thank you so very much for your prompt response and guidance. That worked perfectly. I will definitely look at your blog as I am looking for resources on how to write expressions and learn syntax. In many cases I know what I want to do but being new to Power Apps, I get hung up with syntax and how to write expressions. 

Best Regards,

Mark
