How about:

ClearAll[tmp];
tmp[a_] := Plot[Sin[x (1 + a x)], {x, 0, 6}, Frame -> True]
Manipulate[tmp[a], {a, 0, 2}]

?

Why does    Manipulate[ Plot[Sin[x (1+ a x)], {x,0,6} ], (a,0,2} ]  work....
BUT..... the following doesn't....
tmp = Plot[Sin[x (1+ a x)], {x,0,6} ]
Manipulate[ tmp , (a,0,2}]
I checked Attributes of Manipulate and saw   HoldAll......but Hold what??
thanks.....Jerry Blimbaum
