2D plotting error - This value must be a scalar

I am trying to plot a graph in MathCad which shows how an equation changes with a variable function. When I put in the 2 fields the required functions, the message returns "value must be a scalar".

I have seen this has cropped up on countless times (and apologies that this is a repeated question), however I cannot understand why this is not working. Hopefully someone with a little more experience than me understands why.

I've attached the link for this below.

Thanks
Andrew

Second , in your range variable L should be .. from typing ;.

i.e., your definition of L should be entered as L:0.5m,1m;100m, resulting in L:=0.5m,1.0m..100m

Ah yes, the only thing I did not check in the equations!

You should also get rid of the fix limits on the abscissa and divide in the plot by the desired units.
Using a range variable you will not get rid of the connection (which looks like Mathcad is plotting the asymptote at 3.44m). You may also use the quickplot feature, which normally would give you less control, though.
