comment Plot of a function which includes numerical integrals
@DennisDeClerck you have a variable name pbid1 in the definition of combo, but you have also a global function definition with the same name. This may cause unexpected results.

@DennisDeClerck But from glancing at your code you seem to confuse symbols bound to a function definition with function names already defined.

@DennisDeClerck unfortunately I can't check anything at the moment and for some days to go as my only access to something resembling a PC are my iPad and iPhone.

Also, please note that code can and preferably should be formatted. I've done that for you, but try to do it yourself next time. See the help at the top of this page or the ? Button at the top right of the edit box.

comment How can I convert a list to an expression?
@Mr.Wizard I assume the op1, op2 etc. stand for operator 1, operator 2 etc. so this changes the intention of the question slightly.

comment Is this integration error from a misuse of Mathematica or is it my poor math skills?
The type of integral you want to calculate often pops up when using the integration by parts trick. The resulting expression with a function behind the d is considered by many a (slight) abuse of notation and not mathematically solid.

You can want whatever you like, but you have to adhere to the Mathematica syntax. It expects a variable in that position and what you provide is clearly not a variable.
