# An option must be a rule or a list of rules - error

I want to plot the following code, in 1D. However, code displayed below is not being plotted; no results or errors are displayed

Plot[((16*10^-12)/(4*π*8.854188*Sqrt[4*π*0.125*10^6*t])*(Sum[Integrate[((\[Minus]1)^m E^(\[Minus](x\[Minus]200m-99.5)^2/4*0.125*10^6*t))/(99.5-x)^2,{x,0,100}],{m,\[Minus]∞,+∞}]+Sum[Integrate[((\[Minus]1)^m E^(\[Minus](x\[Minus]200m+99.5)^2/4*0.125*10^6*t))/(99.5-x)^2,{x,0,100}],{m,\[Minus]∞,+∞}])),{t,0,100},PlotRange->All]


code doesn't run. Could you please help? I tried to use Plot instead of Plot3D as i now used just the range of {t,0,100}

• You are using { } in your formula ... why? These are for lists and related constructs - use () if you mean to delimit your sub-expressions with parentheses. Your error is because you have two ranges {t,0,100} and what looks like {x',0,100}. But Plot only supports one range. Do you want Plot3D instead? – flinty Jul 28 '20 at 12:17
• but x' is not the derivative of x Yes which is why you should not write x' because it turns it into a Derivative[1][x]. – flinty Jul 28 '20 at 12:45
