Converting 4.5 stacks to 5.0

[Graham Pearson]

I am trying to convert a runrev 4.5 stack to livecode 5.0 stack which is 
producing an issue for me.

In my stack I have the line

set the bottom right of me to tScreenResultionW, tScreenResolutionR

The values of tScreenResolutionW is 728 and tScreenResolutionH is 1366

What I am trying to do is set the card to the bottom of the screen right 
above the start bar on windows which will float above everything.


When I run the stack I get an error that says

stack "We Are Closed Today Desktop": execution error at line n/a (Chunk: 
error in object expression) near "1274", char 1


Any ideas
