Question - Concatenate 2 variables

Hello,
Is there a built in function that i can use to concatenate 2 variables. ex. var1 contains “0”, while var2 contains “456789”, i want my var3 to show = “0456789”. i’ve tried using the concatenate command: =concat(“$(var1)”+” “+”$(var2)”) but that did not work for me.

We have a lot of built-in functions as well as several string expression which can be found here:

  • Strings can be concatenated; that is, strings can be linked together as in a chain (e.g., “string 1”+” “+”string2” produces “string1 string2” ).

tostring(integer)

This function converts an integer to a string.
