I am trying to check the value of fix versions and throw an error if the version contains an

an .x (so like 5.x, 6.x).  Do you have an example of how I can accomplish this using a sil script?

I use like validator in workflow with transition screen.

if(!hasInput("fixVersions") && contains("Task|Bug|Improvement|Sub-task|Lead Task", type)) {
string errorMsg = "👆 fixVersion!!!";
return false, "fixVersions", errorMsg;
}
