Jus' because I haven't used them in so long, and experimenting is a luxury i have no time for, in a text string how do I do if's in the square brackets?

lol, tried the double equals and it said bad expression =P but your example works, cheers!, how do you do else ifs then? :S lke, ummmm, if 1+1=2 do this, else if 1+1=3 do this, else, jus do this xD

TRUE : FALSE is simply a short hand for the if-then structure. 1 ? TRUE : FALSE is the same as if(1) and as such you can replace the TRUE or FALSE with additional statements, including further if statements. | |
Try that. Look up the ? operator in DM reference.
Essentially, you can shortcut an if statement into
BooleanCheck ? True : False
Generally you'll want to enclose that in parenthesis as I did above to avoid conflicting and confusing order of operations stuff.
Also, your check of "1+1=2" will not work, as the = sign is the assignment operator. Essentially you're trying to assign the value of 2 to the 1 on the other side of the = sign . . . and DM will yell at you :) To compare values, use a double = sign (1+1==2 should always return 1, or TRUE).
