Problem in mate

Hello Every one,

can any one help me out in this, i have been facing this problem in many of my assemblies, i have screen shots of the issue, when i try to make mate (parallel) it gives error, showing the angle at which the part is inclined, wen i freely move the part to different angle & then try the mate (parallel) it gives error considering that angle, But when i just click the angle mate then click parallel it take s the parallel mate, I dont understand why this is happening, kindly let me know if any one have the same issue & know the solution.

Also one more issue i am facing in my system, when i link the equations, i need use two times divid (//) & two times (**) to complete equation then again delete one "/" "*" to get the values.

For example : if i want l x w, then i have to enter l**w then it conisders correct & later i remov one sign *, directly if i enter l*w it shows error, the same problem i am facing for division also. Kindly help me out for this issue.

Regards
