Hi, I have successively done the coding for the radius and boom. I am now onto picking up the weight on this combination. I require a little more explanation on the calculation above. What I have written as a start is the following, I know it needs more polishing, but some help towards it will really be appreciated.
Code:
' WRadius  comes to this part of the code with radius in centimeters (200 to 1600)
' WBoom comes to this part of the code with boom length in centimeters
' bRad_Look have radius in Meter
' WSafe will preferably have the actual value of the weight in Kgs

Get_A:
		If wBoom>550 & wBoom<800 then GoSub Col1A
		If wBoom>=800 & wBoom<1000 then GoSub Col2A
		If wBoom>=1000 & wBoom<1200 then GoSub Col3A
		If wBoom>=1200 & wBoom<1385 then GoSub Col4A
		If wBoom>=1385 &wBoom<1400 then GoSub Col5A
		If wBoom>1400 then GoSub Col6A
Return

Col1A:
		bRad_Look=wRadius/100
		Lookup Rad_Look,[0,0,75,75,57],wSafe
		wSafe=wSafe*100
		If Rad_Look=4 then wSafe=wSafe+50
Return
