Custom Calculation Script code is WRONG!

[Rainman1234]

I am somewhat a newbie when it comes to Adobe Acrobat 5.0. Right now I am trying to make it possible to fill out an OSHA 300 Form on the intranet for my company. I “TRYING” to be nice for my co-workers. I want them to enter the numbers and the form to do the math for them. At column M there are 6 choices (injury, skin disorder, respiratory condition, posioning, hearing, all other illnesses). There are 13 lines per page. I made the 6 choices a check box all named the same. After all you are only allowed 1 choice. In the code you see below I named them line1M through line13M. Here is my problem. At the bottom they want a total for the columns checked. I made the columns exports value 1 through 6. 1 for injury 6 for all other illnesses. I have been trying to properly code the Custom Calculation Script. Below is my code so far... (I know its wrong I just don’t know why! Any and all help is appreciated.)


function calculate(injury) {
var injury = getField("TotalM1");
var skin = getField("TotalM2");
var respiratory = getField("TotalM3");
var poisoning = getField("TotalM4");
var hearing = getField("TotalM5");
var allOther = getField("TotalM5");

var line1M = getField("line1M");
var line2M = getField("line2M");
var line3M = getField("line3M");
var line4M = getField("line4M");
var line5M = getField("line5M");
var line6M = getField("line6M");
var line7M = getField("line7M");
var line8M = getField("line8M");
var line9M = getField("line9M");
var line10M = getField("line10M");
var line11M = getField("line11M");
var line12M = getField("line12M");
var line13M = getField("line13M");

if (line1M.value = 1) {
injury.value = injury.value + 1}
if (line2M.value = 1) {
injury.value = injury.value + 1 }
if (line3M.value = 1) {
injury.value = injury.value + 1}
if (line4M.value = 1) {
injury.value = injury.value + 1 }
if (line5M.value = 1) {
injury.value = injury.value + 1 }
if (line6M.value = 1){
injury.value = injury.value + 1 }
if (line7M.value = 1){
injury.value = injury.value + 1 }
if (line8M.value = 1) {
injury.value = injury.value + 1 }
if (line9M.value = 1) {
injury.value = injury.value + 1 }
if (line10M.value = 1) {
injury.value = injury.value + 1 }
if (line11M.value = 1) {
injury.value = injury.value + 1 }
if (line12M.value = 1) {
injury.value = injury.value + 1 }
if (line13M.value = 1) {
injury.value = injury.value + 1 }

}

Try:
if(oneValue == anotherValue) {
...
...
}

checking for equality requires two equal signs.
