Jan,Thanks for your help. After changing a few things in what you gave me, I finally got all of my v speeds to work correctly.Bill,They sure seem like magic, because when I used the code Jan gave me with the macros, the number came out to be 0, yet when I just used the number the macro represented, it worked.David

Hi Jan,That didn't work for some reason. It seems that the macros I write don't want to work at all. I did however get it to work, sort of. I got it to calculate V1 and put it on the airspeed strip with this:<Update id="V1 Calc"> <script>102 (A:TOTAL WEIGHT, pounds) 82000 - 8000 / 5 * near + (>L:newv1,enum)</Script></Update> And this puts it on the airspeed strip: <Element id="V1"> <FloatPosition>0.000,0.000</FloatPosition> <Element id="V1"> <FloatPosition>0.000,0.000</FloatPosition> <GaugeText id="GaugeText"> <Axis>0.000,8.000</Axis> <BackgroundColor>Black</BackgroundColor> <Bright>True</Bright> <FontColor>Cyan</FontColor> <FontHeight>8</FontHeight> <GaugeString>-1</GaugeString> <HorizontalAlign>CENTER</HorizontalAlign> <Size>20,13</Size> <Transparent>True</Transparent> </GaugeText> </Element> <Shift id="Shift"> <Scale>0.000,1.567</Scale> <Expression id="Expression"> <Minimum>-100.000</Minimum> <Maximum>100.000</Maximum> <script>(A:Airspeed select indicated or true, knots) (L:newv1,enum) -</Script> </Expression> </Shift></Element> That all works fine. But when I start to add any others, either the whole gauge goes blank, or V1 becomes 0.Whenever I put in this line, without displaying Vr on the gauge, V1 becomes 0. Any ideas why? <Update id="SpeedVR Calc"> <script>102 (A:TOTAL WEIGHT, pounds) 82000 - 8000 / 6 * near + (>L:speedVr,enum)</Script></Update> I can't figure out why that would cause the (L:newv1,enum) to become 0.Thanks,David

Hi all,I've been working on adding a few things to the default 737-800 and I'm having trouble getting macros to work. I'm trying to add V speeds to the pfd and have a couple of macros do some calculations to get the speeds based on the aircraft's weight. If I get these working, then I'll add some other calculations to it too.Here's what I have: <Macro Name="baseweight">82000</Macro> <Macro Name="basev1">102</Macro> <Macro Name="incrvr">(A:TOTAL WEIGHT, pounds) @baseweight - 8 / 5 * (>@g:gincrv1)</Macro> <Update> @basev1 (@g:gincrv1) + (>L:newv1,enum) </Update> <Element> <Position X="10" Y="10"/> <FormattedText X="38" Y="12" Font="Arial Black" FontSize="11" Adjust="Center" VerticalAdjust="Bottom" Color="0xF0D0D0" BackgroundColor="#080808" Bright="Yes"> <String> %((L:newv1,enum))% </String> </FormattedText> </Element> I'm trying to at least display the V1 number to see if it's working, but nothing shows up. I've tried various trypes of variables, but none seem to work. I made the (L:newv1,enum) a macro to see if it worked that way, but it didn't.I was originally trying to put it in a shift statement, where it moves a text "-1" on the airspeed strip. Here's the shift statement I tried. <Shift id="Shift"> <Scale>0.000,1.567</Scale> <Expression id="Expression"> <Minimum>-100.000</Minimum> <Maximum>100.000</Maximum> <script>(A:Airspeed select indicated or true, knots) (L:newv1,enum) -</Script> </Expression> </Shift> Again, I've tried using the g: macro instead of L: but nothing works. It seems like half the time the whole pfd becomes blank and the other half, the "-1" text never shows. I know the shift statement works, because at first I was just using a constant number to test it out and get the positioning correct.Thanks.David
