Random range in the random checks is a check between  ZERO and the number you specify, generally. The syntax of the RND command used in this case currently is Int(Rnd * Val(fixText(ifList.Arg(0)))) which may not be exactly what you want under certain circumstances.

if random roll {#0} is equal to {#1}

0 Random range 1 Equal to TRUE if a random number from 0 to {#0} is equal to {#1}.

if random roll {#0} is not equal to {#1}

0 Random range 1 Not Equal to TRUE if a random number from 0 to {#0} is not equal to {#1}.

if random roll {#0} is greater than {#1}

0 Random range 1 Greater than this TRUE if a random number from 0 to {#0} is greater than {#1}.

if random roll is {#0} is less than {#1}

0 Random range 1 Less than this TRUE if a random number from 0 to {#0} is less than {#1}.
