Hello.
Sadly the developer who started this project has quit, and I am desperately trying to get up to speed.
All I want is something simple. Should be one of the most common functions in mapping - to add text inside a graphic as shown. (The map is generated, i put the number in there using paint for purposes of this post)
But as soon as I define a textsymbol, the program bombs. I don't even have to do anything with it, just the var declaration kills it. (See near the bottom of the code)
I have "required" esri/symbols/TextSymbol among others at the top of the script file.
The idea is to place the contents of the HCAD_NUM field from the shapefile near the middle of each plot. But I can't even get it to show a hard-coded "Hello world" anywhere on the screen.
Any help would be greatly appreciated.
