My stored text is working fine. I can use an IF/Elseif with the ${txt}.includes("test") but want to include more terms

This is more of a Javascript version than RPA software. You can use all Javascript operators inside the IF clause!

So the answer to your question #3 is:

${a}.includes("3 months") && !${a}.includes("5 months")

Test macro (See also includes):
