Add 0 to string variable problem

There is a problem when creating a string variable and you add 0 to it. (Preview mode displays correctly, but when published to SCORM, it does not)In short, 1.if y=0,x+y+z=xzExample: "Module 1: + 0 + "%" = "Module 1: %"2. if y<>0x+y+z=xyzExample: "Module 1:" + 10 + "%" = "Module 1: 10%"If the variable starts with 0 and you add text to it, there is no problem, so to get around this problem, I created a new variable (a).if y=0,a= y+zx+a= xaExample:0 + "%" = "0%""Module 1:" + "0%" = "Module 1: 10%"
