How to use label values to reference global table rows in a subflow?

[ FlexSim 18.0.3 ]

the following image describes the labels used in subflow.

the label name Indexx, has a value of 1.00. when the code shown bello is executed the error message pops up saying

"FlexScript exception: cannot access value property on non-treenode Variant at MODEL:/Tools/ProcessFlow/ProcessFlow/Custom Code>variables/codeNode"

code :

/**Custom Code*/
Object current = param(1);
treenode activity = param(2);
Token token = param(3);
treenode processFlow = ownerobject(activity);

Variant reel1 = Table("TerminalCount")[token.Indexx.value][2];
Variant reel2 = Table("TerminalCount")[token.Indexx.value][3];
Variant NoofTerminals = Table("TerminalPerModule")[token.Indexx.value][2];
if(reel1 > NoofTerminals)
{
	reel1 = reel1 - NoofTerminals;
}
else
{
	reel2 = reel2 - NoofTerminals;
}

Remove .value after token.Indexx everywhere in the code and that should fix it.

token.Indexx

is already returning the value of the Indexx label.

You can just use the name of the label to get and set the label's value:

int value = token.Indexx;
token.Indexx = 5;

You only use the .value property on treenodes. You can access the treenode of a label using the labels property:

int value = token.labels["Indexx"].value;
token.labels["Indexx"].value = 5;
