Hi, noob here!
So this is my plan:

generate two random numbers, display them in two different text boxes. (got that working)

generate 4 random calculations like "+", "-", "*", "/"

i did this:

var calcRandom = random(4)
function fCalc ()

if (calcRandom == 1)
{
fCalc ("+")
calctext.SetSelection(0,-1)
calctext.ReplaceSelection(calcRandom)
}

the function "fCalc" that i declared seems to have an expression error. but i looked up the function's syntax and there is no problem.

Are you showing the code for the function fCalc?

If so, a couple thoughts. One, you need {} to start and end the code for the function. Two, are you calling fCalc() from within fCalc?

- - - - - - - -
It is really difficult to solve this when seeing only part of the code, or worse... seeing a piece of code here and another fragment there.
Suggest:
1) use the Code Box to show your scripting when posting
2) when you post code, make sure you provide enough code so that it makes sense.
3) copy and paste code exactly as you are using it, testing it (e.g., maybe you have the '{}' brackets noted above, but you are not showing them here... and then I'm wasting my time picking that out as part of the problem?)

If you are not showing the code for fCalc() here...

...then I assume you have left out the part where you expect the function to receive a parameter. For example:

after i posted this i realised i did not use the correct syntax for to declare my function..

so i fixed it but now i am trying to tell a function that is is supposed to do a calculation like a + or -

//// ////
var calcRandom = Math.random(4)

function fCalc()
{
}

//statement for calculations//

if (calcRandom == 1)
{
fCalc ("+") //how to tell fCalc that + is gonna do a plus calculation??
}

because there will be random calculations generating like - or * when i click


I know im asking stupid questions, I have never in my life done any kind of programming or scripting so stil very stupid with the whole deal

We all start somewhere

1. Learn to use debug: http://www.live.interaktiv.co.uk/index. ... Itemid=166

2. Math.random will generate a number between 0 and 1. (The help is wrong!)

3. String.random will generate a number between 0 and limit.

4. The use of var outside of a function is moot as it only used to scope the variable locally inside of a function.

5. Any JavaScript book up to version 1.2 will help with the basics.

It seems your approach is to 'piece together' a mathematical expression... a + b, or in other cases a / b etc.

However, I suggest you try this more directly using simple logic.

For example, IF case1... myresult = a + b ;
IF case2... myresult = a - b ;
etc.
etc.

I outlined it above and leave it to you to figure out the syntax and the logic flow.

An alternative approach (rather than listing a series of if statements) is to use Opusscript's switch case function. Achieves the same thing with easier (IMO) code.

That makes so much more sence and now that i think about it i was a moron for not thinking of it...thank you
