You need to use the Javascript “Number” conversion to make sure the string content is treated as number, and not as string. This works:
Number (${var1}) > Number (${var2}) + 200
Example:
{
"Name": "greater",
"CreationDate": "2019-9-23",
"Commands": [
{
"Command": "store",
"Target": "100",
"Value": "var1"
},
{
"Command": "store",
"Target": "22",
"Value": "var2"
},
{
"Command": "if_v2",
"Target": "Number (${var1}) > Number (${var2}) + 200",
"Value": ""
},
{
"Command": "echo",
"Target": "var1 wins",
"Value": "green"
},
{
"Command": "else",
"Target": "",
"Value": ""
},
{
"Command": "echo",
"Target": "var2 wins",
"Value": "blue"
},
{
"Command": "end",
"Target": "",
"Value": ""
}
]
}
