Checking If Vars Have A Value?

[LordPorker 7]

I have two variables: Minimum price & Maximum price. Whether these two vars have a value (ie a price) effects the rest of the bot.

 

What's the best way to check if both vars have a value attached? (ie true or false).

 

thanks.

if

var1 = $nothing

then = do action

else = do other action

Try this one

if($comparison(#MinimumPrice,"!= Does not equal",$nothing) AND $comparison(#MaximumPrice,"!= Does not equal",$nothing)) {
    then {
    }
    else {
    }
}

Thank you both, that works great, but I'm going to add a spanner into the works.

 

With the minimum and maximum price input, the user is able to make the bot chose one of four possible paths:

 

1) No price input for either min/max

 

2) Only a price for min

 

3) Only a price for max

 

4) Both prices for min/max

 

How would you check for all possible scenarios?

***Update***

 

Ok, I've added the two vars min/max price together like:

comment("Check for min / max prices")
if($add(#ebay_minimum_price,#ebay_maximum_price) = $nothing) {
    then {
        alert("nothing")
    }
    else {
        alert("price inc")
    }
}

The above will at least check if there is a min/max price value.

Try this one 

set(#MinimumPrice,$nothing,"Global")
set(#MaximumPrice,1,"Global")
if($comparison(#MinimumPrice,"!= Does not equal",$nothing) AND $comparison(#MaximumPrice,"!= Does not equal",$nothing)) {
    then {
        alert("Minimum and Maximum Price != nothing")
    }
    else if($comparison(#MinimumPrice,"= Equals",$noting()) AND $comparison(#MaximumPrice,"= Equals",$nothing)) {
        alert("Minimum and Maximum Price = nothing")
    }
    else if($comparison(#MinimumPrice,"!= Does not equal",$nothing)) {
        alert("Minimum Price != nothing")
    }
    else if($comparison(#MaximumPrice,"!= Does not equal",$nothing)) {
        alert("Maximum Price != nothing")
    }
    else {
    }
}
