Hello. I'm Thomas.

After I go Property and click wiggle(fre, amp, octaves = 1, amp_mult = 5, t = time), I wanted to see the effect.

However,

After effects said it has some error but I do not know exactly what's what.

I need you guys advice, please.

Thank you.

    If you click on the right end of the warning banner you'll see an explanation of the error. You have not set an a frequency or amplitude for your wiggle. It doesn't know how much or how often to wiggle. You can simplify the expression by simply typing: wiggle(10, 5) This will wiggle rotation 10 times a second somewhere between 5º. The other parameters are not needed in most cases.

    I strongly suggest that you type something like "wiggle expression" in the search help field at the top right corner of AE as you start learning expressions. There are a lot of community resources and the help files are pretty good on the subject. It takes a while to figure out what all the methods in the expression language do. You'll never figure it out by just guessing.

    I had that same error, but it turns out I was typing a space in the wrong place, as wiggle (1,1)  should be wiggle(1,1)  wanted to throw that in because as a non-programmer, I underestimated the importance of puctuation, and was following an example shown by someone who I thought was knowledgable.
