Pattern Help - Increases

I am making this dress (http://www.ravelry.com/patterns/library/rainbow-dress–big-sis-version) in size 3T and I need help.

In places, the designer requires increases but hasn’t specified the type of increase. However, there is a section where the type of increase is specified but I’m not exactly sure what is required. This paragraph is for round 6 on the skirt.

[I]Round 6: Knit to marker, slip marker, M1(M1R), knit to marker, M1(M1L), slip marker, knit to marker, slip marker, M1(M1R), knit to marker, M1(M1L), slip marker, knit to end of round.[/I]

Where it says “M1(M1R)”, do I make one increase or two? My first thought is make one M1R-type increase but I want to be sure (cause I HATE to tink).

Just one increase, M1R or L is just the type you should use.
