Searching for issueLinkType.id.contains('10000') and getting a true/false response

[Marie Goodart (work)]

if(issueLinkType.id.contains('10000'){
return true;
} else {
return false;
}

 And I'm getting the error

groovy.lang.MissingPropertyException: No such property: issueLinkType for class: Script708

What am I doing wrong?
