Dodgy link: artist line-up and album musicians

Andrei, it's great - I keep discovering extra features in OCDDB that I never appreciated before.

Like... if you enter info under the LINE-UP tab in ARTIST PROFILE, this will also transfer automatically to the MUSICIANS tab in ALBUM PROPERTIES. Neat, but it would be even neater if the PERIOD field in the LINE-UP section was linked relevantly to a date field. What I mean is this.

Suppose one lead guitarist (G1) played in the band from 1974-1977 (which I enter in the PERIOD field), and another (G2) from 1978-1981. Let's say I enter data for 2 albums, one released in 1975, and another in 1980. Although I have entered the individual albums' release years, and the PERIOD info, the database doesn't register that G1 can't have played guitar in 1980, or G2 in 1975. Under every album's MUSICIANS tab, both guitarists are listed. Maybe there is a link, and I'm just using a wrong date field, I don't know. Does anyone see what I'm on about?!!
