Check for incorrect argument data type or missing argument in call to function 'int'

Trying to conver latitude and longitude into Easting and Northings and this is an error that has occured

[Chunru]

• Break long line codes into shorter ones using ...
• int is not a builtin function. use fix/floor/round/ceil instead (find out the appropriate one for your purpose)
• PI() should be replaced with "pi"
• help sind or cosd for the function with degree argumnent
