OK I have invested in the software and drawn up the design of a circuit I want to simulate/mess about with.
Basically it is powered by a high capacity lithium cell and measures it's own voltage against a reference, two OP amps provide an over and under V trip which turns on the appropriate opto's and a load balancing resistor in the case of an Over V situation.
However the software learning curve is very steep, so I have a number of questions.
1) How exactly do I alter a pot's default value? I can place a generic pot on the circuit and I have changed the VALUE but is that right? I can't find an idiots reference to it in the help
2) I'm also confused about power rails and supplies, the circuit will be powered from the lithium cell which will range from +2.5 to +4.25v. Should I add a battery and wire everything to that?
3) When I try to simulate it I get two errors
5) Also the text in the bottom right hand corner box is overlaying itself and I can't see how to correct it
Just learning so thanks for help in advance. Feel free to correct my errors on the attached and re-upload it

4) I would also like to power the circuit in the simulation from an adjustable 2-5v power supply so I can see if it triggers correctly as V rises or falls, is this possible?No model specified for D1
Simulation failed due to partion analysis errors.
