That was asked and answered a lot. Try to replace the if cond then .. construction by the if is(cond) then ... construction.

For example, compare

if 2*474^(1/2) < 0 then print(1) else print(2) end if;

Error, cannot determine if this expression is true or false: 2*474^(1/2) < 0

with

if is(2*474^(1/2) < 0) then print(1) else print(2) end if;

2

There may be other errors in your code. In order to answer your question, the representation of your code as a text, not a picture, would be useful.
Edit. The second sentence.

PS. The above can be found by the "cannot determine if this expression is true or false" search in MaplePrimes at the top of this page.

Thanks. Works perfectly now.
