Hi Guys,

In the end, I deleted the buggy line and tried to test the rest of the script, and have eventually got it working. My mistakes are highlighted below in case anyone is interested.

Two mistakes here, first you can't assign directly into a varibale from a pattern search, you run the search and then load the value of the MATCH variable, and second, pattern doesn't mean the pattern you are looking for, its actually an expression with its own syntax which must be got correct.

Arithmetic operations must have a space on either side of an operator, otherwise they are interpreted as strings.

All working now with those basic hurdles crossed.
